working until last payroll date that was december the 4th, but today it did not work, please help

Hi there, @accounting697. Let's run some troubleshooting steps to help fix the issue you are experiencing in QuickBooks Online (QBO) Payroll.

If I may ask first, are you seeing any error messages or codes when trying to run payroll? It would also be helpful to know if you're able to access the payroll screen at all, or if the issue occurs when you try to save or submit the paychecks. The more information you can provide, the better equipped we'll be to assist you.

In the meantime, we can rule out the possibility of browser-related issues by opening a private or incognito window and logging in to QBO to run payroll there. This step helps bypass that stored data and fix payroll loading issues.

Moreover, ensure you are using the most recent version of a supported browser. An outdated browser can lead to security blocks that prevent the QBO payroll system from functioning correctly.
