Thanks for the detailed information, tranthaiha1983.
Let's make sure that you are logged in as a Master or Company administrator for you to have the option to close the books.
If you are the Master admin and you get the same thing, it's possible that piled-up cache are causing your browser not to function well. We can do a few browser troubleshooting steps to fix this unusual behavior.
Here's how:
- Let's log in and close your books through a private browser since it doesn't store any cache files.
- If you were able to close using the private browser, we can clear your regular browser's cache.
- You can also use other browsers such as Google Chrome, Internet Explorer or Mozilla Firefox.
Just let me know if you need more help.
