Hi Shamim,
Regarding the “Any role user can access that or all users getting that error?” I already told you 🙂 that “I tried to check all roles before creating this support topic.”
No, I just installed and activated. No custom code. The shortcode “[front-end-pm]” prints that permission error for all kind of roles evet it has the permission or not.
I searched the hook “fep_current_user_can” in the whole file system and the result is no other location than “front-end-pm-pro”.
Thanks
