For some reason, I suddenly get
500 Internal Server Error when I try to add menu item to a menu and I can't figure out why.
I'm running Apache2 with Centos 6 OS on a VPS.
I have PHP 5.8 and MySQL 5.1
This is the error message:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request. (...)
- My error_log file shows nothing.
- I can create new menus
- I can not add pages or custom links to menu items
- I've deleted the .htacess file and get the same error
- I can add new pages and posts
Can anyone help me to figure out what may cause this weird problem?
