Not sure what causing it but the collapsed tables on the classic wiki cooking page are not working for me. Had this problem a few days ago with both the renewal & classic cooking pages and was writing a post when they started worked again so didn't post but now there doing it again.
And this time it seem to only be with the classic wiki cooking page in both firefox and IE. The renewal one is working fine this time. And other pages that are using the collapsing tables (the few i can find such as the content section of each page) on classic wiki all seem to be working fine.
Tried shutting down everything running my machine to see if some program was interfering but nothing seem to be.
