I searched around the forums a bit and tried some of what I could find was relevant with very little luck.
I came into my office this morning and opened my web browser to find that our website was down.
When I try to open any page on the website I get:
Fatal error: Class 'WP_Widget' not found in /home/zemek/public_html/wp-includes/default-widgets.php on line 14
If I try to access wp-admin I get:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster 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.
Please help! I have no idea how to get the site up and running again, never ran into an issue like this before with wordpress on any of my sites. Im just hoping the whole thing isnt pooched!
