Today, I can't vote, at least on Travel.se and possibly on other sites. Sometimes, I get the red "an error occurred, please retry" message and sometimes it appears to work but if I load the page again, the post score has gone back down and there is no indication I voted.
Normally, I reload the page, maybe Ctrl-F5, and everything is fine. But that's not happening today. I have no idea what my next step would be. Does anyone?
