Not too sure when it started, but I've been having the cookie issue for a while now. Although, yesterday I was surprised that I didn't get the cookie message when I went to update my list. This morning I was logged out again. I'm in the U.S.
"Sorry, we've had some problems keeping you logged in. Please clear your cookies, close your browser and try again"
I'm seeing this message very often, with the entire site in larger font. Yes, I am following the directions given to me from the message and the same thing keeps happening evey two to three hours or so. I live in the US. I use Google Chrome.
Every time you change your public IP address, you get that annoying message: "Sorry, we've had some problems keeping you logged in. Please clear your cookies, close your browser and try again".
But if you log off every time you leave the site, it won't appear. Obviously that's uncomfortable, this place is not like Paypal or a bank in which you have to log in every time you do a transaction due to security reasons.
