I was getting the above error when I moved my Magento installation from one host to Bluehost (Hostmonster). What I used to get was nothing on the screen with the error:

<!– SHTML Wrapper - 500 Server Error –>

appearing in the source of the page.

I tried various things like reinstalling the database, reinstalling Magento, tried to see the logs I had access to. None of them worked.

Then I came across a link that said enabling FastCGI option for PHP would fix this. That’s exactly what I did & the bug was fixed. The Magento installation then started working smoothly.

Strangely, I had come across a link that said disabling FastCGI will fix this, but that wasn’t the case.
