Hi,
using D6.14 and Ubercart 2.x
I've 2 domains one the same core (Drupal and Ubercart) but two distinct databases.
The first domain is defined as : site/default, the second has it's URI in site dir : site/dev.domain.com. Database of the second one (dev.domain.com) is a copy of the database of the first site (default)
Both are working perfectly with logged client : cart, order, admin of all...
Only anonymous users on the second one can't make a cart.
Short investigation shows the uc_cart_id is changing on every page ... thus showing a product gives an uc_cart_id and when 'add to cart' is clicked, a new uc_cart_id is generated (session table shows an entry, but no uc_cart_id is saved in the table...)
Any idea to start other investigations or better : a solution 
thanks
Kstar
