Problems upgrading to 3.8 from 3.6
 

Hi*
I upgraded my forum form 3.6 version to 3.8.
Then I installed vbseo but the following problems I think depends on vbulletin.
Now I have 2 problems:

1)
- Me* administrator* try to move a post from a forum to another one* the forum ask me for password again. I insert the password then the post is moved.
- Users report that when they want to open a thread* the forum ask them for user and password.

2)
Now the color palette is no more available.

Can you tell me what could be.
Thank you.
