If I disable the cache on Joomla 1.5 and I publish a new menu item or any other information on the site the new element don't appear immediately after.
If I enable the cache on Joomla 1.5 and I set it to 1 minute delay, and I publish a new menu item, I wait a minute, I do refresh, and I see no menu item.
I only see those new elements, after a certain period of time, regardless joomla configuration options on cache page.
What could this be?
Thanks a lot,

For anyone else that may have this same issue:
It seems that this is something related with Joomla 1.5.x only. Not sure on what configurations. The only way that we found to solve it was to:
If we go to Extensions (or addons not sure since this one is not in English).
Then we click under "plugin management" and then, we need to find the system-cache option, and disabled it.
This could be a broswer issue. I use firefox and used to have a delay in publishing so i got an addon that clears cache with one click.
https://addons.mozilla.org/en-US/firefox/addon/1801/ < that is the link to the one i use. I dont get any issues with delayed publishing.
They are other addons that clear cache and also cookie sessions.
Web developer toolkit is also worthy of a download to help you look at tags, image alts, etc.
Hope this helps.

We have a Magento site running on version 1.7.0 on the Argento theme that seems to be having intermittent issues with products not appearing. This appears to happen on certain pages and not others.
For example, if you add a product from the homepage or single category pages, it will show immediately as being part of the cart (note, Argento uses AjaxPro for the cart). However, once you navigate to another page, say "My Cart" or "Checkout" the total will show as zero. Doing a hard-refresh on the browser will update the total.
Additionally, if you open the Chrome Dev tools, navigate to "Network" and then check "disable cache" everything runs perfectly.
Things we have tried to resolve this:
Flushing/Clearing/Disabling the Magento cache. Seems to make things slightly better but doesn't clear up the issue.
x-cache-control meta tag. Same as above, issue seems to be less frequent but still definitely appearing.
Turn off AjaxPro. Our initial belief was that this plugin was causing issues, but turning it off has no effect.
Re-Index. Has no effect.
Added $.ajaxSetup({"cache" : false}) at the top of our scripts. This also has no effect.
Any advice or tips on where to look next would be appreciated.
It turns out that our hosting provider had set up the installation with the sessions stored in memcache. We switched this over to file storage in our local.xml and it fixed the issue.
I would like to add two new menus to my website, but when I create, or even edit a menu and click Save, Save & Close and Save & New nothing happens.
With Firebug I get
ReferenceError: Hash is not defined
What should I do?
There's a thread here where people have the same problem, and it suggests just clearing your browser's cache fixes it.

That would make sense if you have recently upgraded it and Joomla have updated a javascript file from the previous version.
If not, might be worth seeing if it works in other browsers, to see if it is a Joomla or a similar browser issue.
Failing that, re-install the latest version to make sure you haven't overridden any core files.
When I try to create or edit an article, category, or module, I am unable to save or cancel the changes. When I click on the Admin buttons, nothing happens. The URL gets a "#" added to the end of it, and I get this error (examples from 2 different editors):
ReferenceError: WFEditor is not defined

I have Joomla 2.5.11, no other updates pending. JCE editor, TinyMCE, default, and RokPad all throw errors and don't do anything when I press the buttons. CodeMirror and None are the only editors that I can use to save the article. I have tried uninstalling JCE and reinstalling it, and no changes.
I don't remember the last time it was working, possibly January sometime, if not before then. I don't know if this has anything to do with settings in my php.ini file or not. That was the only thing that changed from the time it was working until now, but it should be back to the "default" settings.
I've tried reuploading the admin folder, but no change. I reuploaded all the Joomla files (except installation) this morning from the stable 2.5.11 package freshly downloaded from joomla.org today, and still having this problem. I've also tried purging cache from the updates manager as well as maintenance area. I've tried 2 different computers, Fire Fox, Chrome, and IE (this was the suggestion in one of the posts I found similar to this issue).
I have been searching for a resolution for months. Any topics I find that sound like my issue end up either not having a resolution, or it's something else that the person is having a problem with. I use both JCE and RokPad on dozens of other websites with no problems.
Thank you for your help.
Do you have extra plugins or modules published on all administrator pages? There could be an extra
Open your console (ctrl+shift+J) and you should be able to locate the error, once you do just try to locate the origin in your code, it's most likely not originating from Joomla core, rather from an extension / template.
Also bear in mind that plugins are active by default on both the frontend and the backend and very often they are not intended to run in the backend, nor tested in the backend.
I JUST FIXED IT!! :) : ) :)
I just switched my hosting's PHP version from 5.4 to 5.3 and voila! It functions as it should. I hope this helps someone! I'm not sure when/why I may be required to go back to 5.4 but for now this solves my problem. Any idea as to why these two versions of PHP behave so differently?
As brilliant as Firebug is, I would consider switching my JavaScript debugging to Chrome if I could figure out how to get it to always re-download styles and images on every visit to the page?
When I'm testing a page in Firefox, it always gets the latest version.
But in Chrome I often end up scratching my head over something that turns out to be a simple issue of the browser caching some earlier styles or images.
Is there a way to configure Chrome to cache less while you're developing?
I often use private browsing mode for this - it prevents caching of the stylesheets or scripts.
EDIT:
Another really easy way to do this in Chrome now is to go into the Chrome Developer Tools, click the settings gear (bottom right), and then check "Disable cache." See https://stackoverflow.com/a/7000899/4570.
A bit late to the party, but just for people who may pick up this page on a search, new versions of Chrome have a developers tools setting to disable the cache. Show developer tools (spanner->tools->developer tools) and on the bottom right is a tiny little gear. click that and a few settings appear in the developer tools window, one of which is to disable the browser cache. If you can't see it you may have to upgrade to a newer version of chrome.

According to Chrome help pages, Ctrl+F5, Shift+F5, Ctrl+R and Shift+R should force refresh. I haven't had problems with javascript and css but refreshing frames is another story. The caching can also be on your web server. The server can obviously be configured to cache css and javascript files.
Your best bet is to clear the cache between each load. With the latest version of Chrome, the hotkey is the same as firefox (on Mac, it's Shift-Command-Del). However, they haven't focused the "Clear Browsing Data" button, so you have to use your mouse to click that button -- which is a total PIA when compared to Firefox (Shift-Command-Del + Return), or Safari (Option-Command-E + Return).
the 2.5 ways i do it are not "automatic" but they're very quick, and i don't have to remember to switch back from private browsing -
a) install Mouse Gestures and use (this is a great extension anyways, but even more so now that I know about) Up, Down, Up - this is a cacheless reload. You can get it here
b) ctrl+shift+r is [supposed to be] a cacheless reload. Even the help pages admit this isn't perfect
c) the .5 is a kind of a hack - but if you are working with CSS files, open a new tab and type in the address to the CSS file itself - you can see what changes are there, as well as make sure that you've gotten the latest one by refreshing this file before your other file. a bit of a pain, i know, but always works.
Not sure about your system but on this WinXP machine holding SHIFT while clicking refresh always forces a complete download.
That's what I do when doing CSS and image tweaks.
That Chrome needs to have must-revalidate in the Cache-Control` header in order to re-check files to see if they need to be re-fetched the way that the other browsers do by default.
Recommend the following response header:
Cache-Control: must-validate
This tells Chrome to check with the server, and see if there is a newer file. IF there is a newer file, it will receive it in the response. If not, it will receive a 304 response, and the assurance that the one in the cache is up to date.
If you do NOT set this header, then in the absence of any other setting that invalidates the file, Chrome will never check with the server to see if there is a newer version.
Here is a blog post that discusses the issue further.
I use Firefox to develop a web site and at the same time to browse the web, read my gmail, etc.
The problem is every now and then I need to delete the cache and or remove the cookies of the web app, but I want to stayed logged in in the other web pages I am visiting.
Do you know a Firefox plugin (or Firefox trick) that can help with this issue?
Preferences → Privacy → remove individual cookies
They are grouped by domain, and you can eliminate all cookies from selected domain with one click.
Update:
Option → Privacy → remove individual cookies
There are two add-ons for FF that every web developer needs and they are Web Developer Toolbar and Firebug, the Firebug extension YSlow comes in very handy too.
Web Developer Toolbar has great cache and cookie control down to individual cookies. Firebug lets you mess with the DOM and CSS directly for a page and YSlow is good for page weight and response times.
Be careful having Firebug enabled for JavaScript heavy sites as they really slow down. GMail will warn you about this and tell you to turn it off. I have had a problem trying to disbable sites with the menus when the tool is embedded in the browser at the bottom but opening it in its own windows the sites menu works fine.
I personnaly also like IE Tab which means I can quickly view a page in IE without leaving FF and I can also get it to load anything that only works in IE with it.
Cookie Monster might work?. Also, have you considered just using two profiles in Firefox? You could setup two profiles with two icons and use one profile for the website and the other for the non-development. The only problem would be you can only have one open at once.
Also, two browsers (Chrome, IE, Firefox, etc) might work well too.
WebDeveloper extension allows to delete cookies for domain. It also can clear cache, although for me Ctrl-F5 is enough usually.
I had the same problem and found a firefox addon to remove the cookies for the current site that you are displaying:
https://addons.mozilla.org/en-US/firefox/addon/remove-cookies-for-site/
Using that I don't have to navigate the firefox menus to find my site in the list (which was too time consuming). This does not cover the cache-issue. For that there is the Ctrl+F5 other people have mentioned. It is covered in good detail here:
What requests do browsers' "F5" and "Ctrl + F5" refreshes generate?
Best solution:
1) Just Click CTRL+H and search the site.
2) right click on it and choose Forget About this site
(source: https://superuser.com/a/733154/249349 )
If you would like to use firefox, clear cache and cookies for one domain and stay logged in (and retain cache) at other sites, you could run a second firefox profile concurrently using the '-no-remote' parameter. I use this all the time to view sites I am building from an anonymous and administrative perspective at the same time.
One way to do this (in windows xp) is: make two profiles, then startmenu->run type 'firefox -profilemanager', untick the 'don't ask next time' box and load profile 1, then startmenu->run type 'firefox -no-remote' and load profile 2. You should now have two seperate firefox profiles running.
Clearing cookies for a single domain is easy with any one of a number of tools. Clearing the cache for a single domain or at the individual page level is sometimes useful, but hasn't turned out so easy for me thus far.
One specific situation is changing a meta redirect, where you can't just ctrl-F5 (you're being redirected, after all). Using a different profile isn't an acceptable general solution. Web Developer toolbar can disable the cache to test that the change is working but it's only a temporary fix, and not one that can readily be suggested to a client in order for them to view the change.
I use SQLite Manager for firefox to remove single sites from cache. All you have to do is open places.sqlite in your user profile folder using this plugin and remove the site. It's not exactly an easy solution but it does work. Make sure you backup your profile 1st!
Ross, I have the perfect answer for you. Get on the current tab that you want cookies cleared. Click tools > Page Info. Or install Page Info Forms & links for a shortcut. Then click the Security Tab. Then View Cookies button. It will bring up all the cookies for the relevant domain. Click the ones you want to delete, and click remove.
Seems we have cookies covered here.
As for cache, the trick is to make your development server force a refresh.
In httpd, you probably have some some cache directives to swap out for these:
Header set Cache-Control "no-cache, must-revalidate"
ExpiresActive On
ExpiresDefault "now"
In header:
<meta http-equiv="cache-control" content="no-cache, no store"/>
The benefit of doing it the httpd way is that your scripts/images/css get refreshed.
In that way you are not restricting yourself to just browser with web developer toolbar, you can use other browsers such as chrome that does not do the no-cache thing so easily.
Another extension that handles the cookie part of the question with a little more ease than the rest is Close'n forget
https://addons.mozilla.org/en-US/firefox/addon/closen-forget
You can use it by toolbar button/context menu/keyboard shortcut in order to close the current page, discarding any cookies it held.
Optionally, the site can be removed from browser history and (again optionally) all the pages you visited in the current page can be removed from browser history too.
Simple solution is simple - use two different browsers.
Say chrome for your email and Firefox for dev.
Also, you have Cookie Swap. but it doesn't really work quite as smoothly as you'd like.
