500 Internal Server Error- Any ideas?
 

Hi guys, i'm getting the following error details when i try to log into my forums. Do any of you have any ideas wht may be casuing it? I originally thought it might be the hos going down, but on the few occasions that's happened in the past i get a 404 error.

Thanks for any help that's given.

There can be many reasons for this, please check your server error log for more information on the details of this error.

A malformed .htaccess file is a common reason for this error. If you are using a .htaccess file, then please rename it to test if this solves the problem.

well, checking the server error log, i have the following error listed several times today.

As you can see, it references .htaccess, so i renamed .htaccess as test as you suggested and it didn't make any difference. In case it helps, this is the contents of ht.access

Any ideas as to why this would suddenly happe now after several yers? ANyway, thanks very much for the help so far Marco.

You probably have more then 1 .htaccess on your server.

There is no 'SecFilterEngine' line in the .htaccess you are listing.

Yes, i thought that was a bit odd.

however, thanks to you pointing out the obvious, the problem has been fixed. Thanks so much mate, you're a superstar.

Any idea why this would happen now out of the blue?

Something must have changed:
- The problematic .htaccess itself
- Something in the webserver configuration

Try to disable mod security or make sure its setup properly and see if you still get the error.
