Endless login/re-auth loop in Firefox (5 posts)

    Hi All,

    I have a problem in some long-standing WP installations.

    In Firefox only, I am stuck in a session timeout/login loop.

    I go to /wp-admin/ it shows me the login screen, I login with a known and working username and pass and then it comes back to the login screen again. This is continuous and I often can not login at all.

    On occasion when I can login, as soon as I go to save a post, I get tossed to the login screen again.

    Additionally If I have more than one tab open on these sites, then I will get the WP session expired dialog. I will login in again via this dialog, but within seconds, the session expired dialog will pop back up.

    I have cleared browsers cache, deleted cookies, deactivated cache plugins etc etc,.. but can not find a solution to this issue.

    Any help appreciated.

    What version of FF do you use? The issue doesn't occur in other browsers?

    I think that might be due to some sort of security kind of plugin you may be using on your wordpress installation .

    Thanks All.

    We have found the problem.. and it was not Firefox or WP.

    Our host added Varnish - http accelerator/cache software - to the sites affected by our issue.

    Removing Varnish has removed the problem.

    FF was 23.0.1 (error on Win 7/FF and Win Vista/FF)
    All security plugins had been removed.
