Nothing shown at back end of joomla admin control panel - joomla

When I have logged in the backend administration section of joomla its showing as such why is it so??
I am totally confused seeing this...
Is this any error
or Any plugin issue...
The site has been Upgraded from 1.7 to 2.5 a month ago..
But then also any hint of such a problem was not seen....

A friend of mine had this issue and I helped him narrow it down.
This problem is caused by fiddling with _viewlevels table in your joomla database. Some plugins/extensions could possibly make such changes as well.
In Joomla Content is classified by who can view/access it. There are three levels of Content Access Classification:
Public - open to all visitors to the web site.
Registered - restricted to all seven Registered User Groups of the web site.
Special - restricted to all User Groups except Guest and Registered.
Administrator belongs to Special. Giving Special all permissions solves thee problem. For some reason, Special class no longer had the ability to access menus of administrator panel in your application.
Edit the Special entry in viewlevels table so it looks like this:
id title ordering rules
|-------------|----------------|-------------|----------------|
| 3 | Special | 2 |[1,2,3,4,5,6,7,8]|
|-------------|----------------|-------------|----------------|

My Views in Dynamics 365 not appearing

When one of our users is creating views with Advanced Find, the views appear in his My Views until he refreshes the page, and disappear after it. I reproduced it on few computers with different browsers and for different entities in CRM. It is working as expected for other users. I already tried to remove and add CRM licenses for this user.
Any ideas?
Finally I created support request for Microsoft. They ran some script on their side and solved the problem.
We experienced this today, shared personal views & dashboards not shown for a particular user.
Removing roles or unsharing/resharing didn’t solve the issue. In all cases, POA table was showing perfect access levels (used xrmtoolbox - search POA plugin). But Access checker xrmtoolbox plugin reveals no access for those saved views (userquery) & user dashboard (userform).
The issue is solved after removing/assigning license in O365.
Another observation: User’s last name changed & asked for AD account modification, our help desk created dupe profile & merged. This could have messed the systemuser entry.

Unable to connect to Magento admin panel

I have an issue with Magneto community and we are using "bizarre" theme. Everything was working fine till last night and I was modifying the categories and products, today morning it seems that there's some issue with admin panel.
When I am logging in with my user id password, it takes me to the index page every time not to admin panel, it works for a while but when I try to go to any settings like "system>configuration> etc" it takes me again to the main page of the website (frontend).
I think you have a problem with cache management.
Try to delete var folder in the [YOUR SITE PATH HERE]/magento/var
Additionally, it might be useful to you. Here is 3 ways to turn on/off cache in Magento

Joomla 3: How to set different user permissions?

I currently have a Joomla site that has 5 different departments of people accessing the backend content. Basically, everyone's looking and poking at other departments contents. So how would I set a different account for everyone and allow them to only modify their own content? E.G.
The salt department can post whatever articles they want, but they cannot modify the sugar department's article.
Does Joomla have this kind of ability or any extensions out there?
That is pretty simple on Joomla 3 system.
Firstly, you create 5 different User Groups in Joomla under Users menu.
Go to Content > Article Manager > click Options button on the top right side > Permissions Tab
In the Permissions Tab, click on each User Group and you have tons of permission to tweak such as: Create, Edit, Edit Own, ...
Hope it helps.
If you haven't configured it yet, the key term to look for is ACL (Access Control List).
Basically you need to create 5 users groups (which are not Super Users).
Here is an article to get you started:

Joomla v1.5.14 Admin top menu elements are missing

My client has Joomla! ver 1.5.14 installed on the remote server. I logged in using the url /administrator/ with login 'admin'. When landed on the admin page after successful login, I observed that the top menu has only two elements, Site and Help. All other elements like Menus, Content, Components, Extensions etc are not there.
Also I do not find any way to access those elements (menus, components). There are not icons on the screen to access them.
Could someone please help me figure out this issue?
Thanks in advance

MulC
EDIT:
Following is the screenshot of the admin page

Thank you
It's very strange that this should happen unless your client has been fiddling with the core Joomla files or database tables.
Update the site to the latest version of the 1.5 series (1.5.26)
Download the full Joomla package, extract the administrator, components, includes, libraries, modules and plugins folder, zip them up and upload to the server, replacing the current folder. Not to worry, this will only override the core files which I assume haven't been edited.
Try downloading and installing another admin template.
Else the only other thing I can think of is reconstructing the website which might take a while, depending on the amount of work that went into it.
In Joomla! 1.5.x a common security step was to create an alternate "super user" and downgrade the default admin account to a standard registered. Due to issues in early versions of 1.5 though it wasn't recommended to delete or disable this account.
This sounds like what is going on with your admin account.
You can check this by looking at the database checking the table jos_users look for the username admin and see what it's usertype is set to. At the same time look for a user that has an usertype of Super Administrator (yes, really the words Super Administrator).
Once you have the username of the Super Administrator, you will need to find the password. If the client doesn't know it then you will have to recover the admin password.

Joomla 1.6 backend admin area blank

For some reason, when I log into my joomla 1.6 backend, it is now empty, displaying only a logout button. Any Ideas?
I just went through the same problem but on J!1.7.3. There may be many, many reasons but please check using just URL if you can see for example:
[YourDomainHere]/administrator/index.php?option=com_content or
[YourDomainHere]/administrator/index.php?option=com_modules
If content is listing and you're missing just Admin-menu and sub-navigation in back-end --> this means you messed-up with access levels and viewing access.
If you can't see content listing - ignore the rest of this post :-)
...with access levels and viewing access. To check that, try entering [YourDomainHere]/administrator/index.php?option=com_users&view=levels and enter each position in the list. Joomla backend navigation module usually has Access set to Special, so focus on this one. When enter Special - manager, author and super administrator should be ticked. If everything empty in any from the list - this is your issue :)
You need to add manager, author and super administrator to your Special access level. Obviously you can't see Save button, so you need to use database. [wrrr :) sounds scary?] Not a big deal, just go there using for example phpMyAdmin and find _viewlevels table. In there just edit Special and add [6,2,8] values to set up manager, author, super.....
Update database. Try to log-in one more time (close browser and clean cache before).
I hope if this wasn't helpful for you, will be for somebody else.
p.s. There may be a way of 'saving' changes in you joomla access levels with URL. Then you don't need to go to DB .. but I don't know if this is feasible at all :)
Check the rewrite of htaccess and the $mosConfig_absolute_path variable in config.php
Apparently, the Bluestork Template (admin template) has some security issues. In my case there were some missing files in the template folder /administrator/templates/bluestork/ that caused the administrator screen to appear blank. I've copied a clean version of the template in the bluestork folder and after that I was able to see the backend admin area.
I've removed the bluestork templates entirely for now, which seems to be the best option. Joomla installs 2.5.8, 2.5.6, 2.5.2, 1.7.0, 1.6.3 are affected. The Blustork Template is a target for hacks with old Joomla.
this happening becoz of admin user lost his permissions. see below article to fix this issue
