Summary:
If You Add A Custom Field To A Resource You Can No Longer Edit The Resource
Detailed Description:
Once you add a custom field to a resource you can no longer edit that resource,
you are instead presented with the following error:
Fatal error: Call to undefined method cge_array::array_merge_by_keys() in
/modules/Availability/action.admin_edit_rsrc.php on line 531
I have deleted all my resources and added new ones and the problem still occurs.
It does not happen unless you add a custom field.
