I hope this is the right place for this...
After my traffic started increasing, 'Internal Server Error' messages started randomly showing up now and then.
What should I do?
"Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, firstname.lastname@example.org and inform them of the time the error occurred, and anything you might have done that may have caused the error.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request."
