Some members get Error when trying to login

[63 Sprint]

We recently had an upgrade to 2.1.1  and some members get Error when trying to log in. Others, and myself included don't have this problem.

Please open the attachment below to view a snapshot.

We hope there is a simple fix.

Thankyou,

Did the error ocurr only after upgrading to 2.1.1. immediately, or did you install a mod prior to it? Is there any specific error pertaining to this logged in at the error log?

Do you force the url to be www in .htaccess?
