Mandatory information about my setup:

Have I read the related troubleshooter articles above before posting (which pages?)? Yes - nothing touches it.
Have I searched the tickets before posting? Yes
Have I read the documentation before posting (which pages?)? Read the whole thing
Joomla! version: Joomla! 2.5.6
PHP version: Joomla says its 5.2.17 but GoDaddy tells me it's 5.3
MySQL version: (unknown)
Host: GoDaddy
Admin Tools version: 2.5.6

Description of my issue:

A while back I posted this post (12335 – Homepage is blank (but will load with a refresh) regarding an issue I was having with my client's site: http://speakourlanguage.com/.

What happens is, the homepage frequently loads completely blank, especially after a browser cache clearing or when we log out of Joomla's backend. It almost always happens to people who visit the site for the first time, which is obviously rather a bad thing.

After an immense amount research, we've finally figured out that it must be some sort of conflict between Admin Tools and a component called Smart Slider. When we disable the Smart Slider module on the homepage, the issue goes away. Conversely, when said module is enable and the Admin Tools system plugin is disabled, there is no issue.

Can anyone think of why this might be happening and how we may work to avoid this in the future? I really like both components so I'd hate to have to stop using one of them. I'm happy to provide login details to anyone who asks. Thanks so much!!!

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.
