Man, really?

Use "install" instead of "remove".

Tony, to be honest, what I would do, take a backup and then start with a new and fresh server. That's the main benefit of the cloud model.

And of course, you now have a very important lesson learned to not remove core webinoly packages manually. You better use the proper Webinoly commands to install and remove packages.

Regards.
