How old is your iPad?
Certain sites, if their permissions are
too up-to-date, break or are otherwise inaccessible to older Browsers.
Learned the hard way from my Wii U (I was in the same boat as
@Cutie Gwen for a while, needing to use my Wii U to access certain sites because I lacked access to my laptop) and my Phone (an old Blackberry).
Wikia breaks on Wii U, for the record, and you can't access "vignette.wikia.nocookie" which means the images don't show up.
It
probably has something to do with HTML5, if I had to guess.
