Thread:Project:Support desk/"Server encountered an unexpected condition" when running update.php on CGI

Hello, I have MW 1.17. When I try and run the update.php via, , I can get through most of the options, but when It's time to update tables, I get the following error:

The server encountered an unexpected condition which prevented it from fulfilling the request. The script had an error or it did not produce any output. If there was an error, you should be able to see it in the error log.

Why is this happening?! I'm on MediaWiki on a shared web host (iPage).
