and once I ( CTRL + U ) , I ( CTRL + A - CTRL + V ) , then save changes, I go back to the weeworld tab, and I only see top half of the site, I see Home, Friends, Shop, etc. But not the closet nor the clothes, How do I fix this?"

The only reason that this would occur is that you are not replacing all of the source code. Make sure that you erase all of the source code in Opera, and copy all of the source code in Closet Swap. If you don't erase/get every last bit of it, it will not load the page correctly.
