Hi there, Deanna.

I've checked all the article links attached on this thread, and it seems like I was able to open them successfully. Let's perform the basic troubleshooting which is to open your browser in incognito/private mode to help determine if this is caused by a browser. 

Here are the keyboard shortcuts to open a private browser: 

• Google Chrome: press Ctrl+Shift+N 
• Mozilla Firefox: press Ctrl+Shift+P 
• Internet Explorer: press Ctrl+Shift+P 
• Safari: press Command+Shift+N

If you're able to view the links with private browser, I suggest clearing your browser's cache to start fresh. The next time you log in to QuickBooks Online, your browser will download fresh copies of everything you see on each page. Any cache-related issues should be cleared up.

Please let me know how it goes. You're always welcome to post if you have any other questions. Have a good one.
