Error after module update

[pasi]

I was running the module update to update the modules as shown in the screen capture.

While the update was running, I accidentally closed the web browser where the update was running.
After sometime, I was able to log back into the admin console on from a web browser.
At this time the Dashboard did not load the System Overview panel and the Apply Config button become available at the top right corner.
When I clock on the Apply Config button, I ran into this error.

exit: 1
Exception: Unable to locate the FreePBX BMO Class 'Pm2’A required module might be disabled or uninstalled. Recommended steps (run from the CLI): 1) fwconsole ma install pm2 2) fwconsole ma enable pm2 in file /var/www/html/admin/libraries/BMO/Self_Helper.class.php on line 216

I then rebooted the server itself and the issue still persist.
Calls are still working.

How can I get the system back to normal?

Thank you,
