Hi,
Creating multi-language Virtuemart can be tricky if you don't know what you are doing.
But this has absolutely nothing to do with our template. Unfortunately we don't provide free support or step-by-step instructions if the issue has nothing to do with our templates. Simply because we didn't develop the Virtuemart Component, we are developing templates for it.
Read some articles and guidance about how to setup multi-language Virtuemart websites:
