I was trying to run Snapshot but got this error... help.

I've never used this backup system before and just wanted to make a backup before I start adding additional plugins and tweaks to my site but I got this error.

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

Please contact the server administrator 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 Server at growinggreat.org Port 80

Is this something that I need to configure through GoDaddy or with Wordpress?

Thanks!
