I always seem to have this problem on my host. I followed instructions and uploaded 3.21 upgrade and set CHMODs as requested, but I still get this error when trying to call the pl from the server:
"Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@chandlerpd.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."
I use Hostway as my ISP.
