upgrade to 1.6 broke my store

When i updated to the 1.6 code (at least I think it is 1.6, cannot find version number in the admin panel, downloaded it 4 days ago) all of my "buy" buttons disappeared. Any short answer on how to get them back?

Hi,

Check in HikaShop > Configuration > Display if the option "Display 'add to cart' button" is enabled, and check it too in content menus & modules in HikaShop > Display > Content menus / modules.

Thank you, that got it. Apparently the upgrade reset some of the parameters.
