Is this the right place for help with a 500 server error message?

The post below is my first post here ever. I submitted this question a while ago, and it seems like my issue has been overlooked. If this question is inappropriate for this forum, can you please link or direct me to another internal WordPress source or even an external source. I realize that everyone here is a volunteer, and am grateful to have access to this support, however if this is the wrong place to get it answered, I just need to find a solution elsewhere (although I doubt that will work either!)

Thanks!

Trying to install WP 2.8. I’m hosted at Startlogic. I’ve only installed WordPress (2.7)once before there, and didn’t encounter this problem.

I went through the 5-minute WP install procedures and got through the “Install WordPress” and was told

“Success! WordPress has been installed. Were you expecting more steps? Sorry to disappoint.”

However, as soon as I try to log on, I get this message:

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.

I don’t see an error log in my high level WP directories.

I checked MySQL and as user I have full access. My suspicion is that I may have a permissions problem.

Tech support at Startlogic won’t help since it is a self-install (they don’t offer WP 2.8), so I’m turning here for help. I hope someone has some ideas what may be wrong.

Thanks.
