I am tired from this problem (I don’t know if it’s specific to firefox or not).

As some time passes after I log in to my site (of course, I check "remember me". ), I have to log in to my site again. How to stop WP from asking me so frequent logins? Like Facebook does – you log in and that’s all until you log out.

I’ve tried add_filter('auth_cookie_expiration' .... but it didn’t help.

p.s. I use iThemes Security (if it matters).
