Hi all! And Happy Xmas! :-)
I've done just some tests, but no way ...
1) clearing my browser’s cache
2) third-party cookies enabled
3) all browser extensions or add-ons temporarily disabled (started in "safe mode")
4) enabling HTTPS
still it doesn't remember my password.
Here you can see some screenshots:
(a) - "Remember me" doesn't work
WP_login_000 - http://wordpress.com/
(b) - "Remember me" doesn't work (simply refreshing - twice - the log-in box changes position)
WP_login_001 - http://wordpress.com/
(c) - "Remember me" WORKS!
WP_login_002 - http://en.wordpress.com/wp-login.php
So, if I arrive into WordPress by "http://wordpress.com/", it doesn't remember my password, on the other hand, if I use "http://en.wordpress.com/wp-login.php", I can have my password!
The configuration is the same in the tree situations.
My browser is FF v 17.0.1 and, like O.S., I use Windows 7 Professional or Windows Vista Business.
I hope this could be useful.
