I have gotten this "General error pls refresh and try again" message for several hours now.
I have cleared browser history+catche etc (everything) as well as FlashPlayer catche.
I have refreshed the page over and over again.
I have restarted my computer.
I have logged out of the game, waited half an hour before logging back in.
I tried three different browsers, one of them I normally don't use at all.
And the last thing I did this morning was to start a new adventure... :/
I wasn't able to send any generals 'cause the game froze.
After that I haven't been able to play.
