Everytime I give a like, a notice comes up "There was a problem storing your reputation vote", but the like is still there. Why is that?

I had that happen also, it was usually after clicking the "like this" fast and thus twice.

Agree. You'll get that message if you try to like something you've already liked, which happens fast if you don't make just one clean click.

Just tried 'liking' MJCM's post twice, quickly, júb júb, and got the same message.

But I have a hard time believing that this has nothing to do with possum1931's reputation.

I mean, even I have a difficult time taking him seriously sometimes. Can't imagine how non-AI software like ThaiVisa forum server handles his requests.
