Thread:Extension talk:Collection/Clicking Disable triggers Product Version MediaWiki 1.22.2 (66e64fc) PHP 5.3.15 (apache2handler) MySQL 5.0.77

MediaWiki	1.22.2 (66e64fc) PHP	       5.3.15 (apache2handler) MySQL	       5.0.77 Collection     1.6.1

Starting the Create a Book function works, and the addition of pages works, but clicking Disable returns " Fatal exception of type MWException".

Enabling verbose errors doesn't show anything extra.
