I tried to search for this problem but I didn't get any good hits. My forums are currently not functioning, the index page will load but nothing else will load and there are no error messages. I can't get to the admin panel or anything. I have been running phpbb for years without an issue.
I have a basic hosting account through dreamhost so I don't have shell access or anything. I logged into phpmyadmin and the database is up and appears to be working fine. I am not sure what to try from here.
The forums did break last thursday, I was attempting to use the prune feature to prune some old posts and it timed out during the prune. Then I started to get this error message and it only went away after my host rebooted the web server and sql server. The forums worked fine again for 2 days.
This is the error I was getting last thursday after the pruning went bad:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

and inform them of the time the error occurred, and anything you might have done that may have caused the error.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
