Hey there, @lisa-2i-t-com. 

It's great to see you back in the Community! 

Let me ask you some additional questions so we can narrow down the cause: 

• Have you been able to successfully edit other projects in the system? If so, what details are different in each of the projects? 
• Have you tried signing out and then back in? 

This will help us determine the cause of this issue and get you on your way with your projects in QBO. I'll be waiting for your response!
