Hi
I am running EE 2.5.2 and MSM 2.1.3.
Since I upgraded (I think it was from 2.1.3) I have an randomly occurring issue when trying to login to the CP.
Sometimes I am unable to login with without given any error message. Clearing the browser cache fixes the issue.
The problem occurs using both login url’s (default site and second site)
I use for both sites the admin.php as the login method.
Thanks
