500 - Internal server error after install

[agustealo]

I've installed VM2 and all was great until at some point while I'm adding products I hit refresh and BAM!!!! The dreaded 500 - Internal server error.

Here is a link to site http://stevenland.com/

Everything else works like articles and anything else not a part of VM2, except for the Administrator area (it's 500 as well).
