I have had several customers who have not been able to login to their account. I spoke to one via my live chat. I actually watched him sign up for his account. The account was created, but then immediately in told him that his session had expired. He tried to log in again and again but it kept booting him out, telling him his session had expired and go to the time out page. I thought it was the SEO mod I had installed, but I deactivated it and the problem persisted.

I am using zencart 1.3.02. We went live a week or two ago and have had several customers a day with the same problem.
