[SOLVED] Cart not working anymore

[aleph]

Hi guys, I don't know what happened but when I try to add some products to my cart, I can see there are products in the upper right line showing only the number of the products in the cart, but in the cart module there are no products and no prices.

I've tried to replace the blockcart with the last backup and to empty the DB tables relative with the cart, but it is the same.

I've installed some module lately, and after each install I've checked if all was working. Probably I haven't checked enough well

Now I don't have a backup and don't know how to do.

Anyone has any idea what could it be the problem?

thanks.

Ok, at the end I found out it was the UPS module that changed something in /classes/Cart.php
Changed back to the original file and problems solved.

I have the same issue but I guess it was easier for me to find the problem since I make backups of the files that are changed before I install new modules.

I really NEED the UPS module to work for my store so I have to get this problem resolved. Did you find a solution as to how to use it with UPS?

Could the UPS module and Cart block work together? Has anyone found a solution. I need both to work, too.
