Many pages are missing material.  One example: Of Mice and Men Unit 

Missing are links to YouTube videos (put on the page using the function on Weebly's "build" options) and links to other websites with articles on the author, historical info, etc.

Hi @MrsBradley everything appears to be loading okay. There's only on Youtube video that is set to "private" that won't load. Can you try opening from a new browser in private/incognito mode? If you are using a school network, you might want to try testing with mobile data. It's possible your school blocks Youtube servers? 

The page loads but is missing videos and links to other texts.  On the page I linked to (Of Mice and Men Unit) there should be cartoons showing how Warner Bros. took the character of Lennie and turned him into the Abominable Snowman etc..  On my Beowulf unit page an iMovie compilation a student made is missing.

I don't see the Beuwolf page, but this is what I see for the cartoon parody: 

I'm not seeing that since yesterday; not on my MBP or Chromebook; not in Safari or Chrome browsers.  Other videos are missing too.  Same page, further down.  

This is what I see when I scroll down. Can you try accessing the site from a different internet connection?
