Entityqueue - Handler drop down is empty after installation I have just installed the Entityqueue module on my drupal 7x site. However, when I go to the /admin/structure/entityqueue/add page, the Handler dopwn down is empty and therefore the form will not validate so I cannot create a new list.

I've checked the \modules\entityqueue\plugins\entityqueue\handler folder and the simple handler is present along with it's class file.

Help!
I uninstalled the module but it was still appearing in the Modules list and I could not re-install it for this reason. However when I re-enabled it and saved, the Simple Handler appeared in the drop down. Good grief.
