Sometimes, particularly in the mornings, I can't even log into my account. I don't see it happen on craigslist. Come on backpage, you're growing too fast to be that slow!
It worked for me too after a while. It just sometimes I try to log in and it goes to the message ... something about encountering a problem and that I should use the Back button and try again in 5 minutes... If it happened once a month, I'd say no problem. But once or twice a day - it's a problem they have to address.
