I have Internal Server Error with my site:
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.
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 have wordpress blog on this site.
Only one page of my site is working, and admin panel is working. The main page and more than 300 pages are with errors.
What can i do to delete this error?
