upgraded to 5.4.2.2, cannot login to concrete5 site

Permalink
Hi, all

I upgraded the concrete5 site to 5.4.2.2 from 5.3.3.1, then i cannot login to the site.
Enter the ID and password, press the sign in button, but admin bar isn't displayed.
Access to dashboard, login page displayed again.

I read this page (http://www.concrete5.org/documentation/how-tos/developers/i-cant-lo... ), reset admin user's password, but still can't login.
I don't have other idea. Does anybody know this problem?

thanks

Upgrading note: You need to be running version 5.3.2 or later to upgrade to 5.4.2.2. If you're before that version, first upgrade to 5.3.2.

Thanks you for reply, but I used 5.3.3.1, so later than 5.3.2.

And, I watched Users table, when I try to login, uNumLogins number was incremented. Is this mean I can login, but logout immediately...???
