Cannot modify and save order

Hello everyone,

I was changing a few things under Utilities - System Manager - User details, and now after I modified or edited an order, I cannot save (the save button is grey).  Any suggestions?  I changed  "Modify Order" back to "NO" because I wasn't even able to invoice and now I can.  But that didn't solve the save/modify order issue.

I copied another user's account and created a new temporary account for myself and I am able to do my work; however when I changed the values of my old account according to another user's values, it doesn't solve the issue.  Ideally I would like to keep my original account.

Thanks!
