I put my admin user into the staff category and now I can only login to the "staff" page with all my accounts.
How can i fix this?
Try looking in your database in the table: ost_staff
Here you will find your admin user, and you can change it. As an example, set isadmin to 1. You can also change the group_id or dept_id if you want.
thank you I did the same thing and this saved me!
