Hi @kwangmoklee Thanks for commenting on this post! For the payroll missing, we would recommend restoring a prior backup of the file. @Lucius  comment is a great suggestion. We would then check Payroll and Sales Journals. Here are some helpful articles for restoring a backup:

Restoring the automatic backup created during either conversion or update in EasyACCT

How to back up and restore EasyACCT company data

If there is still something going on with Sales Journals and Payroll, please report back here so we are able to capture the feedback and report back to the appropriate teams.
