I'm not sure when this started as We don't normally have a need to edit existing email templates. Today I went to edit a email template, after all the needed changes were made I pressed the save button which produces the error "Not Allowed". This error occurs when editing or creating new email templates. I check the permissions for admin, all are set to you can create and edit email templates. I've searched the forums and have had no luck finding a solution. Any help with this would appreciated.
Solution was to remove the old action hook that put in place to stop emails being submitted with the {php} tag.
