 * The “Collapsing Categories” widget isn’t availible anymore after the wordpress
   upgrade to 4.0.
 * Even if after re-install and activate the plugin, it doesn’t show as an option
   in Presentation -> Widgets section.

 * I see the same problem. I had to roll back to 3.9.2 since Collapsing Categories
   is crucial for me.

 * The symptoms I think all of us are seeing (in WP 4.0 only) are that after installing
   the widget (yes, I tried deleting and then reinstalling the widget) it simply
   does not appear listed anywhere as a widget, not even as an inactive widget, 
   and not even as one that is available to activate anywhere.
 * My installation of Collapsing Categories had silently survived a number of previous
   WP upgrades (from 3.8 through 3.9.2), so this behavior is unique to the ->4.0
   upgrade step.
 * Does anyone have different symptoms to report?

 * I’ve got the same symptoms. Upgraded to 4.0 and “poof”. Deactivate and reactivated,
   no avail.

 * Same as all of the above…
 * Hopefully Rob Felty will update the plugin. If so, please reply to this item 
   so we can be notified.
 * Many Thanks!
