I originally had an issue with the permissions and it not allowing anyone (Thanks to your issue logs, I was able to fix that portion).

However - I can not seem to the GUI to load. Even after I make sure /fc toggole on has been completed. Even when using the /craft or /fc craft command, it still does not load for any of my users

I believe I found my issue as we were reviewing some other mod and issues. I uninstalled PermissionsEX and installed group manager. added all the permissions in the appropriate location, and it seems to be working now for all after the toggle on.

Thanks!
