The cart is cleaned on its own

[yusi4ka]

Dear Sirs, Could you please advise me of some problem with the cart?
When I send several items of goods into the cart (sometimes 16, sometimes 18), it is cleaned on its own without our doing anything. We add different goods into the cart. No changes in the cart files have been made.
Virtuemart version is 2.0.6.
Website is http://topcomfort.ru.
Thank you in advance.

This was quite a topic in version 2.0.6 however I believe that the quantity in the cart has been fixed in 2.0.8 versions

I have updated Virtuemart and virtuemart-aio to 2.0.8. Error remained the same. The cart is cleaned on its own.
