Sorry, one more quick thing in SpecialCategoryFunctions.php :
Line 35: $m_place = editFormTextAfterWarn;
Line 38: $m_place = uploadFormTextAfterSummary;
Probably mean something like this:
* $m_place = "editFormTextAfterWarn";
* $m_place = editFormTextAfterWarn();
* Something else.
All the best,
Nick.
