Quickbooks online unable to view subscription javascript void error

Glad to see you again here in the Community, @Koj.

I'd like to make sure that you'll be able to view your billing subscription successfully. 

The error that you're getting can be caused by the corrupted data that are stored on your browser. Web-based platforms like QuickBooks Online collect cache files for faster browsing. However, too much may lead to unusual behavior.

To fix this, you can access your QBO using a private window. This lets you utilize your data on a clean slate. If it works fine, you can go back to the regular browser and clear its cache. This eliminates the unnecessary file to prevent this hurdle from happening.

For your reference, I have here some links that you can scan through to guide you in viewing and updating the billing details in QuickBooks Online:

Let me know if you have any other questions. I'll be right here to help whenever you need one. Have a good day!
