Forum:Unknown problem for logged in users?

In my wiki, I have used a lot "collapse" function (as it's a singer's wikia, so "collapse" for track listing). However, when I was logged out, the "collapse" function worked. When I was logged in, it doesn't work, even the show/hide button are disappear! Can anyone help?Thanks a lot. \^/AR\^/IC&#124;&lt;ENNY 14:27, July 1, 2011 (UTC)
