I updated a client's network from 3.0 to 3.3.2 for (obvious) security reasons. Since I have updated, I haven't been able to access the network admin page. I have a 500 error generated by a PHP Fatal Error :
[error] [client CLIENT_IP] PHP Fatal error: Call to undefined function get_current_screen() in /path/to/wordpress/wp-admin/network/settings.php on line 22, referer: http://DOMAIN/wp-admin/index.php
I followed the instructions given by Ipstenu. Nothing worked. Here's a list of the things I tried :
- Disabling plugins
- Make a manual re-install
- Make a fresh install
- Repair and optimize DB
- Check permissions
- Check if there are no conflicting usernames/emails
So now is the point where I can't get further by my self and need help.
If useful, here are bits the server config :
OS: CentOS 5.6
php -v : PHP 5.2.10
mysql -v : MySQL 5.0.77
This should be sufficient for WP 3.3.2 (even if a bit too old for my liking).
Anybody got an idea?
Thanks in advance!
