error message index 0 out of bounds for length 0 message when running payroll

Thanks for visiting the Community page, Carmel. I've got some troubleshooting steps to fix the issue you're having while trying to run payroll in QuickBooks Online (QBO).

I recommend performing some basic troubleshooting instructions to see if it's a browser-related issue, as QuickBooks experiences unusual behavior due to stored internet cache files. Let's begin by opening your account in an incognito or private browser window and completing the activity again.

Here are the keyboard shortcuts for popular browsers:

• Google Chrome: Ctrl + Shift + N
• Microsoft Edge: Ctrl + Shift + N
• Safari: Command + Shift + N
• Mozilla Firefox: Ctrl + Shift + P

If it works, go back to your regular browser and clear its cache. Clearing the cache or cookies is the best way to start fresh and ensure optimal performance. Otherwise, using other supported browsers can be a good alternative too.

If the issue persists, I recommend contacting our Live Support team. They have the appropriate tools to conduct a comprehensive diagnosis of your account in a secure setting. Furthermore, their expertise enables them to identify the cause of the issue and provide the most effective solution. 

I will also include these comprehensive collection of help articles to streamline your payroll process:
 

• QuickBooks Online Standard Payroll | Resource Hub
• QuickBooks Online Advanced Payroll | Resource Hub

With the information above, you'll be able to successfully run your payroll. I'm still around to back up if you need further guidance or clarification.
