Always is added the same product

[tioserch]

Hi.

 

I have got a problem.

 

I have begun to operate with the web and a client has told me that cannot buy the Web because not added the selected product but which increases the amount of the first product selected.

 

I have been doing evidence and I have seen that if I add products from product_info do it right.

 

Another thing that I have seen is that if I add the first product does so well, since the second only adds units to the first, with which is not updated the value of product_info. If I make a log out and I log in with the same customer data and therefore with basket full, when I add another product is added correctly, and by adding the second returns to fail by adding a unit to the last product. The error must occur when I do click on "Continue buying" in the basket.

 

Please, can you help me?. It is urgent. Thank you.
