However, when I switch from the main site to the meta site on my main machine (running Arch Linux and Firefox 33) I am getting logged out. When I click "login" in the navigation bar the page refreshes, but I am still logged out. When I click "sign up" I get redirected to the sign up page for the main site (even though the navigation bar shows my reputation and badges again, indicating I am logged in).
I tried clearing the cache and deleting cookies from
emacs.stackexchange.com, but that did not help.
