HI there,
i see you helped with a ticket on this 2 months ago.
so i did the steps in that ticket
https://wordpress.org/support/topic/forbidden-error-with-gravity-forms/#post-13344339
but unfortunately i am still seeing the pop up error after reinstalling the plugin.
the Error Disappears once we have CleanTalk is deactivated
Any Advice you can give would be greatly appreciated
