Something's not right with my sessions, can't figure out what.
When you enter my site ([url removed, login to view]) and you try to add an item from the homepage, it won't add to the cart.
If you retry, a session is created and you can add to the cart.
I have had messages from customers who say they can't add to the cart at all, or items disappear from the cart.
However, I still receive orders.
-I have seo-urls installed, but the problems also occurs when switched off.
- I have sts-template, I am not sure this if the problem lies here. STS is used for the header, but this is since a few months. Before this, the site showed the same problem.
- The sessions are stored in my database (set in both configure files)
- And I have the "force cookie" in admin set to false.
The project is to fix the whole session problem.
Please bid only if you have serious experience in oscommerce and know about sessions and their behaviour. This is urgent, since this problem causes a loss of potential customers.
