Before the update of my template, I could add "complementary products" in a virtuemart product, in order to publish it in the pop-up cart.
Since an update of the template:
- It is possible to select a "complementary products" in admin for a product
- But when I save a product, the "complementary products" is not saved !!!!
Is it a problem about plugin, Javascripts ? Other ? It is a big probleme for me at the moment...

Best regards,
Jérôme
