Help Fully Uninstalling this plugin's changes to the WordPress Database.
The plugin created the "Role" Event Contributor and a ton of capabilities, ie. Edit Ai1ec Events, Edit Others Ai1ec Events, etc. I cannot delete this role, or any of the capabilities because when I try, I get the following error, "A valid role name can only have letters, digits and spaces" ??
Additionally, I cannot change any of the permissions for the Role. How do I fully delete this plugin's additions from my WordPress Database?
