I'm having the same issue. I went back and redid all the edits, and still get the same thing. It was working fine until I upgraded from 3.5.1 to 3.5.3

So, it looks like what is happening is that instead of the reputation popup window disappearing after you hit submit, it reloads itself. So the reputation is submitted correctly, but when the window reloads, you get the "Can't give reupatation to the same post twice" error.

Any ideas on resolving that?

dont know bro, im workin on it too

any help????

I wish I could help you. In my case it reloads the thread in the reputation window after I submit it. Frustrating, isn't it?

i got all of it, but it wont open up in a new window
