I cant accept friend request on battle.net or in game

when i click on accept it tells me that my friend list is full remove a friend, well i removed like 100 friends and all pending friend request that i sent but it still shows me the same message.

Yeah . I’m also having the same problem. I’ve got only a total of 140 friends in list , 0 requesting, 0 black lists but i can’t accept any friend invitation
