I have a problem, in the category bar when I select the number of results to show, it brings all the products and shows only the category.
thanks

This functionality is core VM - nothing to do with our templates - templates just display the info supplied by the server..

you can try with puremart disabled to check

Please can you test with Puremart completely disabled.
To do this just rename the folder

ROOT/templates/YOUR_TEMPLATE/html/com_virtuemart

to

ROOT/templates/YOUR_TEMPLATE/html/com_virtuemart2
