Hi Fashion.
Can you share with me as to what page did you get the error message?
In the meantime, let's try opening QuickBooks on a private window. It is the best place to identify browser-related issues. You can use these keyboard keys to open one:
- Google Chrome: Ctrl + Shift + N
- Mozilla Firefox: Ctrl + Shift + P
- Microsoft Edge: Ctrl + Shift + P
- Safari: Command + Shift + N
If it works, you can go back to a regular browser and clear its cache. A piled cache can also be the reason for some unexpected issues on the opened pages like QuickBooks. You also have the option to switch to a different browser like Google Chrome, Mozilla Firefox, Safari, or Microsoft Edge.
Also, feel free to browse our Help page for some guide in managing your QuickBooks account.
I'll be around whenever help is needed. Keep safe!
