[SOLVED] Sort by manufacturer not work with multilanguage viruemart 3.2.2

[Ventsi Genchev]

After updating virtuemart 3.2.1 to 3.2.2 "Sort by manufacturer" not work.
Can someone else confirm?

[Milbo]

in the FE? product browse view?

Hi, Milbo.
In the product browse page and only in a language other than English (bulgarian).
When the page is in English, everything is ok.

When the selected language is Bulgarian (it is default), only 1 manufacturer is shown in the browse page. No option to choose another.

If I include a manufacturer selection filter (I use Custom filter Pro), I can see all the manufacturers. If I choose the same manufacturer, there is no problem. But if I choose one of the others - white screen with a message: "Unsupported operand types".

I finally found the problem.
Everything comes from the option "Dual Fallback".
After updating the VM from 3.2.1 to 3.2.2, this option appears and is checked by default. When turned off, the problem described above disappears.

Not that I know exactly what "Dual Fallback" does.
Can anybody say something about it? What is this option for?
