PLEASE HELP!! I PAY A BEER! Edit product(FRONTEND&BACKEND) = AUTOMATICALLY UNPUBLISH!

Hi:
Please, help me!
I have problems, I try to solve and do not see how.
Updated to the latest version of Joomla, Jomsocial and Quickcart.
1. As from the view of admininistrador stores frontend (multivendor) a product, to save or save and exit, the product will automatically unpublish .

I tried several solutions, check the documentation Quickcart, search the forum, etc. Anyone else happens? Some small clue as to where to go?

thanks
