Virtuemart products module breaks

[pm4698]

Hello there,

I have a joomla 2.5.x, virtuemart 2.6.x website.

Take a look at this:

As you can see at frontpage, you see below first slider 3 buttons (fb, red and green boxes). Below this, i use a tabs plugin for joomla, where i load 2 modules (latest and featured virtuemart products modules).

Exactly below this, i load virtuemart featured products module alone, without any tabs.

Why when i try to use those or other tabs, the modules show the products vertically and not horizontally like below tabs module?

Is there a conflict?Is there something you propose to do in order to fix this?

As i wrote, i have tried also tabs from other manufacturers. I have the same result.

Thank you in advance and i appreciate your help

Open your Virtuemart Module then change Products per row to 4.
