Error 500 on every page but home

I’m installing a Yii site for a client on the host 1&1. The home page loads perfectly, but every page I try to go to from there gives me this:

Error 500 - Internal server error


An internal server error has occured!

Please try again later.

The code is the same as what I have on my development site hosted by Bluehost, which works well, so I’m rather confused as to why this is happening. Some of the actions I try to call are page actions with separate views, while others are actions with a view. Either way, though, when I try to var_dump and die at the beginning of those actions, I find that it didn’t even reach that point before it threw the error.

Does anyone have an idea what to do about this?

Configure log component (if you haven’t done it yet) and check protected/runtime/application.log for more info on the error.

Ok, so the reason this is happening is due to my urlManager. I have it set to

'urlFormat'=>'path'

and that breaks every page other than the Home page. I can turn that off, and everything works, but I lose that feature.

Any help here?
