Product page is messed up

Hi,

I do not know what happened here, but on my localhost everything works just fine, while on the live site its messed up. I need some help.

As you can see on the screen shots, on the first screen shot the additional pictures are just all over the page, and I wish to use it as it is in the original out-of-the-box (OOB) layout.

The tabs have disappeared for the ask a question and the product reviews. I kept all the OOB products enabled. The change is on the whole site independent if my newly created product or the OOB one.

As additional, the products are not to update anymore

What I have done: I have compared the OOB version with mine and the differences are:
- Products in the row: 3
- Added 1 new shipper: USPS (and created a free shipping option)

The rest are the same
