I see it perfectly. Which browser do you use? Do you use an ad blocker?
When you enter to the Wiki for the first time, a pop up window appears warning you of the spoilers, and you need to press the button on the right to accept that and continue; otherwise you will only see the top part. If in a previous ocassion you pressed the left button or for some reason your browser is blocking the window, then you can't see the articles.
@EternalLocket: Hmmm, it's weird. I use Firefox too (on Arch Linux) and can see all the articles without problem. Did you erase both cookies and cache? Also, from the "Time range to clear" drop-down menu, you should select "Everything".
