Hi, I have a problem when I add related products.

Choose the relates products and I click on save changes.
But not save me related products. The products chosen are cleared.

Joomla 3.3.6
Virtuemart 3.0.4
php 5.5 and 5.4 (I tried with 2 versions)

Any idea what could be happening?

thank you very much!

Hello PRO,
thank you very much for your help.

I tried "install or update tables if necessary" and not fixed.

Then I tried "Reset all tables and do a fresh install" and resolved. Thank you very much!
