Does anyone know if there is a problem with quickbooks: the page is not loading and the drop down menu on the sales and expenses pages is not working. Any ideas?

Hello, fberry_skindr. 

Thank you for bringing this issue to the Community. I've checked with my resources and verify with the engineering team, we haven't received any similar issues reported in QuickBooks Online. However, we can perform some troubleshooting steps to fix this.  

There are times that the browser is full of frequently-accessed page resources, thus accumulating and corrupts the browser cache causing the run time user interface to malfunction.

To start, access QuickBooks account using a private/incognito browser. You can use the shortcut keys below: 

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

If it works, we'll go back to your regular browser and clear the cache to get rid of the stored junk files. You can also use other supported browsers as an alternative and to roll out the possibility of a browser-related issue.    

For additional reference, you can use the following article to personalize invoices in QuickBooks: Customise invoices, estimates, and sales receipts in QuickBooks Online. 

Let me know if you have other concerns that I can help you with. I'll be around. Stay safe!
