Problem with Adding Products in Virtuemart

Hi

I have an install of Bikestore up and everything was working fine until I opened it today and can't add/edit products, category's or manufacturer's in Virtuemart.

As you will see in the pic attached the tabs dont appear on the top of the page for the different pages like images instead they follow down the page. As do the menu on the left , it's all showing whereas the tabs should be collapsed.

Then nothing happens when you try save

Any idea's, i dont want to have to start over with a new install of the quickstart package but might have to if necessary

I don't think it is template issue but just some VirtueMart bug. Please ask your hosting about changes in server configuration and contact with VM support forum. To make 100% sure that it is not template issue you can switch template to Beez.
