Hello. When trying to modify a wikiset I get the following error:
[653537a6] 2012-11-11 14:07:16: Fatal exception of type MWException
I asked fellow steward Billinghurst to test if he had the same problem, which he confirmed me.
Aditionally, you can't delete items in the second box "Wikis not included above".
This is an important bug since we need to change wikisets from time to time and this bug does not allow us to do so.
Thanks for your attention.
