How to update safari cache? - caching

I have moved my Prestashop website from one domain to another. And during the DNS UPDATE, which some time takes 24 hours, few/many of my costumers visited my website during DNS change process and the website didn't open for 100%. The issue is only for safari users, now after website works perfect, even for mac with safari browsers.
Those who had the issue during DNS change, now cant visit my website through safari. Now I am thinking of a way to fix this issue. Any ideas please?

Microphone Permission on Firefox Mobile not permanent

I am facing an issue with our web tool that I am unable to solve. I already tried to google a solution but failed to find one.
We have a website where we use JavaScript to record audio from the users microphone via getUserMedia. The first time the user enters a html page on the https website, there is a notification popping up about permission rights. Thats fine, but on Firefox Mobile it doesn't matter if you gave your permission already, you will be asked on every single page again. Thats not the case for every other browser we tried.
So, is this some kind of our error or is it a limitation of Firefox Mobile?
Hope anyone solved that issue already in the past.
Best regards,
Daniel
It's a limitation in Firefox for Android (fennec). It intentionally asks users each time.
It's being solved in the next generation version, available in beta as Firefox Preview (fenix). The prompt there adds this checkbox, similar to Firefox for desktop:

Strange joomla mobile site behavior

Till 2 days ago, everything was great with my Joomla site (web shop), but now I have strange problem. Don't know if it is hack, malware, or something else, but here is what is so strange:
When I am looking and browsing on desktop site (on my laptop or desktop computer), everything is OK and no problem, also, when I am looking trough site with my mobile phone or small tablet everything is still OK, but when I press "back button" in browser, it doesn't take me back on my mobile web site, but starts jumping trough several web addresses and then ends on some address that is some kind advertise or "download this" - "download that" stuff.
Everything is OK on mobile when I am going in forward trough menu, trough shop item and putting it to cart, but every time I press back, it doesn't matter where I am on web site, or from which device is browsing (iOS or Android), first time I press "back" it goes to some advertise site.
There is no problem on my mobile device if I put site to "browse as desktop version". When is desktop verison, also on my mobile device I can go back and advance trough site, but as soon as I put it to "mobile version" (responsive), back button is just "hacked".
Is it possible that this is somewhere in my code? Because I have replace all theme files again trough FTP, also, I have made site restore from several days ago and still same problem.
I did not touch my server, because everything is OK with desktop version, so I assume that this is problem somewhere in code for mobile version.
Did any of you stump on similar problem? I have searching trough web for similar problem last 2 days but nothing even close to this one :/
I'll appreciate for any kind of help, this site is really very important to me and I have insert month and month of hard work in it... :(
Thanks in advance.

My web page all of a sudden opens only partially and cannot be changed

Vista 32; IE9; FrontPage 2003. I've updated my web page for years on a daily basis. Today, after updating my web page only displayed less than half of the Home Page. All other pages of my web page worked. Other computers were able to open the web page normally.
I tried to change the Home Page and uploaded, but the result was the same. I refreshed the page, I restarted and new-started the computer,no difference. I've spent several hours trying to fix the problem myself, but to no avail.
Thanks for any help

Unfortunately I realized too late that I was in the wrong forum. You're right, it's of course not a programming problem. PLUS: today everything works without any changes having been made. There are more things in heaven and earth, Horatio,...
Thanks for all your efforts

Magento ecommerce: Can’t login to admin or add items to cart in Safari 5.0 on a Mac

I am dealing with a very particular issue on a newly built Magento ecommerce site (running version 1.5.1), www.azaturechocolates.com.
My client is unable to login to the admin panel or add items to the shopping cart in Safari 5.0 (on a macbook machine). However the site works fine for them in Firefox.
I have tested multiple Safari browsers (PC, Mac, Macbook, version 5.0, 5.1) and cannot replicate the issue, the site works well for me. The site also works fine for all other browsers, IE, FF, Chrome.
We checked the clients’ cookie settings and security settings and all seemed normal. Also, we cleared the cache and cookies several times with same results.
Any ideas or suggestions on what could be causing this issue and how to fix it?
Try to increase session life time to few days. Issue can be dependence on different time zones. So try to make session life time as long as you can try, for experiment.
Hope it'll help.

Website Images That Are Cached In Chrome Disappear On Page Refresh

I'm having a strange issue with Chrome.
I'm working on development with a very image heavy website. If I reload a page over and over again, eventually half the images or more will just disappear. (they don't seem to be broken, just not visible).
If I clear my local cache in Chrome and refresh the page, the images return.
Any idea what may be causing this and how to possibly fix?
edit: just to note, it's not just me. Others hav reported the same issue on the website I'm working on. Always Chrome.
Images, which contains "content-length" header randomly disapper, removing this at the server side solves this bug...
(chrome dev team has this issue in "open" state in their bug tracing system)
I've been getting this recently too. I generally use the latest dev channel for Chrome and assumed it was related to that, but even when launching the regular version of Chrome I get the same issue. I've only noticed it for the past 2-3 months though. Hard-refresh does the job, but it's a really odd bug.
