"The server encountered an internal error..."

[Toomas]

Hi,

I got exactly to same message while trying to install GetSimple for the first time today.
Installation goes well up to the point where login details are sent by email. The following page "support.php" fails to load with error message described above.
Same thing happens when trying to access admin page, or just the front page of the site.

My first guess was that this is somehow related to file/folder permissions, but don't know for sure yet.
