Media Wiki update from 1.15.x to 1.22.x
I had to update an MediaWiki server due to security issues:
Things I had to do to get it working:
Added in /etc/my.cnf
net_buffer_length=1000000
max_allowed_packet=1000000000
To make import possible from database dump.
Placed new mediawiki server next to the old one. Copies the images en plugins.
Run from the commandline php update.php
All went well.
