everything dandy with SS, except that when I refresh a page i get a "Internal Server Error" and the following message:

"The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, support@supportwebsite.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Apache/1.3.33 Server at sistematisa.com Port 80"

Then when I refresh again i appears normaly, then hit refresh and same error, and so on...

Extra info:
hosting on godaddy deluxe linux
tested on firefox 3
Windows XP machine

EDIT: just tried with IE 7, it doesn't have this problem, :? can anybody explain what's wrong when viewing in firefox?

yes i've tried, still intermitent error when refreshing...

I was experiencing constant 500 Internal Errors on GoDaddy shared hosting, I found a thread talking about the same problem and edited the HTTP.php file like it said, and it worked wonders. The site is no longer throwing 500 Internal Server errors.

Here is the link of the thread:

Hope that helps
