I happen to read through some good posts by someone, and just as being appreciative, i pressed on Up-Arrow (positive arrow). For some time like 1 or 2, it worked fine, but later As soon as i pressed it, both arrows disappeared. It happened like 2 or 3 times with the same person (He is a mod).
I don't think its a vote limiter in Daniweb, if it were, it would have been just limited to reps, there would not have been any problem in up-voting alone, right?
So what is causing this?
