Solved Internal Server when creating new Topics - no problems (when deleting topics)

Do-you have restarted apache after that you have edited the php.ini ?

I had two issues that kept me from installing it. I failed to edit the correct php.ini file (I needed to us /etc/php5/fpm/php.ini, and I had failed to restart apache2 and php).

It installed correctly now, but I'm still getting the same error:

Internal Server Error

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

Please contact the server administrator at [no address given] to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

and in apache2/error.log

As I said earlier, it's always taken a while to create a new post (many times longer than deleting one), but it didn't used to time out. We have moved to fastcgi recently, and that's when the timeout error cropped up. We've been advised to run joomla with fastCGI, so I'd like to be able to get Kunena to work with FastCGI.

Thanks - I've got to go offline for about 45 minutes, but I'll be back then.

Try to enable debug mode in Joomla! and Kunena to see a better error message

I'm tailing the /var/log/apache2/error.log while I create a new topic. I don't see anything happen when I first press the submit button. However, the page just hangs there, saying, "waiting for host." Then, the 500 error occurs at the same time as the following lines are written to the log:

I'm seeing errors all over the page, but they appear before I actually get the error that led me to the forum. They appear as the page to create a new topic loads (but not as it gets submitted):

looks there is a bug on module mod_light_rss, please disable it and try again.

I've disabled mod_light_rss so the errors referencing that module have vanished.

However, I'm still getting the same 500 Server error, after a delay of about 30 seconds to process my posting/submitting of a new topic, or replying to an existing topic.

The file /var/log/apache2/errors.log contains:
