[Forum] Intermittent 500 errors

[joshtrav]

We are noticing a lot of 500 errors that are intermittent since we swapped to vBulletin. Is there a setting we can check that is too short of a timeout, etc? It is occurring enough that at this juncture its becoming a true annoyance to our community.

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

Those are server issues. You need to contact your host and ask then to check the server error logs.

Ok Steve, I took a look at the logs and this is what all the files are saying when it does:
