Restart the iPad. Close all other pages and apps. See if the problem persists. 

Apple has an unsolved memory distribution issue with ipads, laptops, and desktops, too. Their system software just gets bigger and bigger. Less memory is available for apps and web pages. So, in some instances, the device runs out of memory BEFORE all the css and javascript on a webpage can be downloaded or executed.

Of course, Apple with their silly commitment of minimalism at all cost, is not going to give you a friendly pop-up box telling you what the simple problem was. That's YOUR problem, not theirs.

(Most of their devices leave the factory with WAAAAY too little memory because memory is their highest profit product. They want to sell you more at the beginning and do not even allow for extra chips to be added later. In most cases, that is. Few exceptions.)

Try your memory intensive front page on other computers, such as windows or linux. I have had the same ongoing problem with the iPad as you do now. Of course, it could be something else behind this frustrating issue.

Good luck, Tim.
