Unexpected token < in JSON at position 0
Thanks for dropping by the Intuit Community, 123146138226669.
The message occurs when the file you’re running or saving has contents that don’t meet JSON guidelines. When the browser’s cache is overloaded it affects QBO performance.
I can help you get back on track by performing the browser troubleshooting steps. You can start by opening your company using a private/incognito window.
If you can use QuickBooks without any issues, go back to your regular browser clear the temporary Internet files/cache.
Then, close out of the browser to start on a clean slate. This article will walk you through the steps of clearing the cache based on the browser you're using: How do I clear my browser cache and temporary Internet files?
You should be able to perform any processes in QuickBooks smoothly.
Keep me posted how these steps work for you. I’ll get back to you if you need further assistance.
