This is on meta. On certain questions like Rename [screen] to [gnu-screen] I see the question but unable to put my preference or opinion on it as it says I'm logged into unix.stackexchange.com and stackexchange and elsewhere. I'm not even able to get a correct login page for the meta.unix.stackexchange.com site. Going to http://meta.unix.stackexchange.com is also unhelpful. I also tried registering in the hopes that something might be broken or dis-connected and maybe I had to re-register again but nothing. It dumps me right back to the homepage. I don't even get any questions for signing up.
Can somebody help.
Update - It is a HTTPS-Everywhere issue. After I take out the two HTTPS-Everywhere rules about stackexchange it works.
