Thread:Project:Support desk/Fatal exception of type MWException - different

Hello,

I have 1.22.2, Mysql 5.1.66, php 5.2

Basically, I tried to install this extension http://www.mediawiki.org/wiki/Extension:Chklist

I'm sure I did it right (uploading, editing the settings) as I have several others. Unfortunately unless I remove it from the local settings it shows me

[letters and numbers that are always different] 2014-02-20 02:59:30: Fatal exception of type MWException

is it because it can't work on mediawiki 1.22.2?

Thanks
