Glad to have you here, and I appreciate your proactive approach to resolving the issue before seeking assistance within the QuickBooks Community, mamu52.
Accessing your QBO account in a private browser, clearing the cache, and switching to another supported browser typically resolves errors and any unusual behavior in your QBO account.
Since the error persists, I suggest reaching out to our Support Team to help us investigate the error that occurs when making edits to the company address information. Here's how:
- Within your QBO account, go to Help in the upper-right corner.
- In the Search tab, click Contact us.

- Enter a brief description of your concern.
- Click Continue.
If you encounter any other issues while making changes to your QBO account or require assistance with different tasks, please don't hesitate to inform me. I'm here and available to assist you.
