Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.
Apache Server at www.xxxxx.org Port 80

Check your server error log and also your Joomla error log. Post back with errors please.

There is nothing in Joomla error log. I don't know where to look for server log. It doesn't give the same error when I submit a message as site admin.

I fixed this by changing my Joomla directory to 755. It was set to 775.

I have all permissions set as 755 by default. Must be something else.

@ alemdag:

Internal error comes usually when apache cannot process the request.. Usually it's something that you have in htaccess (redirect?) or in your apache configuration (wrong alias etc).

Apache log can usually be found in /var/log/httpd or /var/log/apache2 (file is error.log, error_log or something similiar). The latest log does not have 1.gz or similiar in the filename..

Just ssh into your system and get tail from this file:
tail -f error_log_filename

Then use your browser to post a reply and look from the console what is logged.
