[Forum] forum acting weird after update to 4.1.7

[the dark room alive]

i had to admit that i had a vbulletin nulled version 4.1.4, but just for try, i recently buyed the licence of the forum, so i updated the forum to 4.1.7, but since them, this things happend in the forum:

• some users cant log in, even if they log in with facebook, they get the message "welcome back user" and then when the pages reloads they have to sign in again.
• when someone try to change the default skin, the page reloads with the same skin, they have to enter a threat so they can see the change

what can i do to solve this?

What's the Forum URL value set to in AdminCP > Settings > Options > Site Name / URL / Contact Details - the www or the non-www version of your domain? What URL are they using? What do you have in your Cookie Settings?

Are you using memcached by any chance, or any caching engine?

i deleted the old database and installed 4.1.7, clean install, i will import the tables that i need and i will see if i can fix the problem, after having problems with importing selected tables , i had to restore the old databaes, and im still having troubles
