I think you have a different issue. Try disabling the "System - System Restore Point" plugin. This issue affects only Joomla! 3.0.2 and later. It will be fixed in the next release of Akeeba Backup.

Let's make sure that the problem is indeed caused by Admin Tools. In order to do so, try the following:

1. Try setting the Error Reporting level in your Global Configuration to "None". Many errors are caused by harmless PHP Notices and Warnings being output to the browser, breaking anything which requires HTTP header manipulation such as Joomla!'s session management, AJAX calls and download systems.

2. Try to replicate the issue after disabling the "System - Admin Tools" plugin. If you can still replicate the issue, it is not caused by Admin Tools. Disabling that plugin means that Admin Tools code (including the Web Application Firewall) is not running on your site.

3. If you suspect an issue with the .htaccess file, replace its contents with the contents of the stock htaccess.txt file shipped with every version of Joomla!. If you are on GoDaddy please wait for 1-30 minutes for the changes to be effective. Then, retry loading the problem page. If you can still reproduce the error, then it is not caused by .htaccess Maker.

If doing any of the above resulted in the issue still occurring, it's not related with Admin Tools and I can't help you. If doing any of the above did stop the issue from occurring, we'll have to do some troubleshooting.

First go to Admin Tools, Web Application Firewall, Configure WAF. Make sure "Log security exceptions" is set to Yes; if it's not, set it to Yes and click on Save. Now try reproducing your issue. Immediately after that, please go to Admin Tools, Web Application Firewall, Security Exceptions Log and go to the last page. The last log entry should have the date and time of when the issue occurred. Please copy the Reason and Target URL here so that I can help you.

If, however, you do not see a log entry, or the Date and/or IP address do not match your last access, this problem is not caused by Admin Tools' WAF. In this case, you will have to do some .htaccess troubleshooting. You may need to read the general .htaccess troubleshooting page, as well as the page on finding out necessary .htaccess exceptions.

I would try to disable system plugins to find out where the problem comes from. According to my experinece, this kind of code:

$option = JRequest::getCmd('option', 'com_foobar');

in a system plugin has the potential to cause that problem with some extensions. Since Joomla! 3.0.2, JRequest's get* methods do modify the global $_REQUEST variable with the default value being passed to them. Plugins have got to use JFactory::getApplication()->input->get(....) instead. The only reason I found this out is because the "System - System Restore Points" plugin (shipped with Akeeba Backup Professional) did trigger this kind of bug on Gantry-based templates. I am sure that Gantry is definitely neither the first nor the last extension to use the internal redirection trick as I'm sure that "System - System Restore Points" is not the onyl plugin to use JRequest to fetch query parameters.

I hope that helps!

OK. You can now send my previous (technical) comments to the JomSocial guys and I'm sure they'll fix it a.s.a.p. :)

Ah, I see what you're doing there. Living on the edge. Cutting edge CMS, not officially supported software, the works ;)

Makes sense :) Keep up the good work!
