Mandatory information about my setup:

Have I read the related troubleshooter articles above before posting (which pages?)? Yes
Have I searched the forum before posting? Yes
Have I read the documentation before posting (which pages?)? Yes
Joomla! version: (1.5.24)
PHP version: (5.2.8)
MySQL version: (5.0.91-community)
Host: (Soho - UK)
Admin Tools version: (2.1.10) was 2.1.8 before I just updated it


Description of my issue:
Suddenly, starting today, I've received a lot of complaints regarding one of the websites we have done and installed Admin Tools Pro onto. This site had been already hacked twice before we took it over.

It seems to work fine with Chrome, but when I try to access the site with IE8 I get :


Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/MySite/public_html/index.php:19) in /home/MySite/public_html/libraries/joomla/session/session.php on line 423

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/MySite/public_html/index.php:19) in /home/MySite/public_html/libraries/joomla/session/session.php on line 423

Warning: Cannot modify header information - headers already sent by (output started at /home/MySite/public_html/index.php:19) in /home/MySite/public_html/libraries/joomla/session/session.php on line 426

Warning: Cannot modify header information - headers already sent by (output started at /home/MySite/public_html/index.php:19) in /home/MySite/public_html/plugins/system/admintools/badbehaviour/screener.inc.php on line 8

Then the page with strange characters appears.

I haven't updated anything on MY computer (but I've had a LOT of complaints from others all with the same or similar problem) including the error lines and just a blank white page. I checked the logs and there doesn't seem to be any sign of anyhthing having been hacked. I haven't changed anything on the site and it would seem it was working fine until a few days ago.

Does anyone know what the problem is? It's obviously Admin Tools related

In the Configure WAF page, set the "Enable Bad Behavior filter" to "no". That doesn't fix the problem, but it should let your IE8 users use the website.

Well, I wouldn't jump the gun and assume that the problem lies with Admin Tools. The problem here is that you have enabled GZip compression in your Joomla! Global Configuration. In order for this to work, Joomla! needs to set an HTTP header to instruct the browser that it should uncompress the stream it is receiving before parsing it. Some script is outputting at least one byte before Joomla! has the chance to do that, hence the strange characters.

Which script does that? Let's take a look at the error message:
headers already sent by (output started at /home/MySite/public_html/index.php:19)

So, the script in question is Joomla!'s index.php itself, on line 19. On a stock Joomla! site, line 19 is a blank line. This leads me to believe that your index.php file is corrupt.

Go to your back-end, Components, Admin Tools and click on the Joomla! update icon. Then, click on Reinstall 1.5.24.

If this doesn't help, please send me a PM (I'm user "nicholas") with the following information:
- A link back to this thread so that I know why you're sending me the PM
- URL to your site
- Super Administrator username and password
- FTP access information, i.e. hostname, username and password
so that I can take a look.
