I tried repping a user from a thread in the help section and something went wrong. I can see the little space where I can put a comment with the positive feedback, I click submit, the text dissapear but nothing more... No confirmation like before (+rep was given), check the status of the user, rep=0. Someone, please take a look at this ! Thanks !
I've gotten that problem a few times before. I think it has to do with the type of text in the comment you give. Try giving the rep w/o a comment.
I think it also has a character limit on how much you can type in the box im not positive but i think it might. Also as Zer0 said it might have a character limit on which characters are aloud in the box
