I'm unable to create a new account in the chart of accounts. Also unable to edit them.

There are times when QuickBooks online is poorly configured, @ifacosta. It might be that there was a glitch in your QBO. 

In the meantime, I suggest using a private window that doesn't store files. Browsers use cache and cookies to load web pages faster.

To open an incognito window, you can refer to these keyboard shortcuts:

• Google Chrome: Press Crtl+Shift+P
• Microsoft Edge & Mozilla Firefox: Crtl+Shift+N
• Safari: Press Command+Shift+N

If you still have the same result, I suggest utilizing another supported browser. It will help us identify if the issue is specific to your current browser.

When you can edit and add a new chart of accounts, consider returning to your regular browser and clearing its cache and cookies.

I'll be here if you still have questions about your charts of accounts. Have a great day!
