Pages no long displaying

Im running the curse of strahd campaign and have done a lot of work on the various pages and all of a sudden none of the pages are loading. it looks like it goes through the process of loading, black screen telling me its loading and all. but when its done i only see the roll20 background. not sure what i did or how to get all the pages to show up for me again.

ive also tried creating new games with the preview wildemount and I also cant see any of the pages in that game either. i suspect this is some sort of browser issue? im using firefox. really dont know what i did to mess things up tho. any help to get my pages to show back up would be greatly appreciated.
