# Collapsing isn't working…No function named error

 * I was screwing around with my site trying to get other plugins to work and apparently
   I ruined my Collapse-O-Matic. Not sure what I did and of course I don’t have 
   a backup.
 * Here’s my site:
 * [http://vintageland.com/mencollection/](http://vintageland.com/mencollection/)
 * The left sidebar has buttons that list each era and when you click on them they
   should expand but don’t. I think I made some changes to the script in either 
   my head or footer which caused the problem.
 * Today I tried a fresh install of Collapse O Matic and I’m still having an issue.
 * Through Firefox I see that I’m getting this error many times and I think this
   is the issue:

   > location: “native frame :: <unknown filename> :: <TOP_LEVEL> :: line 0” data:
   > no]
 * Any help would be greatly appreciated. I’m not sure what I have done to screw
   this up. Thanks for your continued support.

 * I have also recognized that a lot of the plugin files are marked as inactive 
   on the plugin editing page even after a fresh install.

 * Matt,
 * The issue is that your WordPress intall does not support livequery:
    `Uncaught
   TypeError: Object #<Object> has no method 'livequery'`
 * simply roll back to [version 1.4.9](http://downloads.wordpress.org/plugin/jquery-collapse-o-matic.1.4.9.zip)
   of the plugin until we release an update that addresses this very issue.
