I am completely new to Wordpress! Sorry for my lack of knowledge...
I'm getting this error, no matter what I click...cannot access dashboard or admin:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, cgiadmin@yourhostingaccount.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.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.
I looked at my server error log and this is what is coming up:
