Hi,
I have the same error (please view post https://www.itthinx.com/topic/groups-illegal-offset-type/)
I tried Antonio solution
Groups->Options:
1.- Deselect all post types, and Save.
2.- Re-select all post types and Save
but it doesn’t work.
My groups options SETTING is
Administrator Access Override: On
Post types: All On
User profiles: On
Tree view: Off
Permissions: Administrator all ticked, others various role (but not “restrict access” role)
Deactivation and data persistence: Off
Legacy Settings: On
Thank you
Hi Tatiana,
Maybe just like Jeremy (the first topic author), you have a conflict woth another plugin. You can try to deactivate all your plugins and then activate them one at a time until you get the error.
Kind Regards,
Antonio B.
