How to Fix the issue - Friend invites (READ)

for those who think it's bugged or something else, it's caused by adblock. if you got adblock. and turn it off to accept the friend invites then turn it back on. problem solved.

also, turn it off if you are trying to make a post, unable to add a image to the post. make sure ADB/ADP is off. :D
do the same if you are deleting comments and more.
