Virtuemart 2.0 administration layout problems

[admiss]

Hi,

I need someone, how is really prof in Virtuemart, and coding.
I use VM 2.1.22b, with joomla 2.5

I was looking for solutions for several problems, and at the end I mess the VM admin layout 

When I add a new product, the problem doesn't occur.
But if I want to edit some existing(uploaded) product, the field appear strange.
The field
Product Information
Product Description
Product StatusProduct
Dimensions and Weight
Product Images
Custom Fields

are not showing side by side (separate, in tabs), but on one page, under one another.

This kind of layout can be seen also in "Shop"-Shop.

Could anybody help me?

Looks like you have a JavaScript issue, possibly caused by some third party plugin.

Note that your VM version is known to have critical security issues, so you should seriously consider updating. http://forum.virtuemart.net/index.php?topic=118683.0
