I am just using 1 admin and 2 standard accounts. The problem is for the 2 accounts, no problems with admin, I can use and modify anything in studio and all changes are saved, but just for the admin. The 2 standard profile cannot post, cannot ask for friendship and when I send a friendship request for the admin account the 2 profiles get the request but when they try to accept it, the message they get is input data isn't defined. Moreover, the user can see the notifications but when they open it, it says empty. I have attached 3 screenshots to my previous message.
