Printer Safety Check is disabled

What is the problem?
I had my printer safety check disabled because I had a A8 with stock mainboard and firmware.
Now I have the same printer with an SKR v1.4 mainboard and Marlin 2.0x bugfixed.

My question is: How can I enable this plugin?
Or do I have to reinstal Octoprint?

The Printer Safety Check is a bundled plugin. It should just be a simple matter of enabling it.

Thank you, I'll try it tomorrow.

Cant find the plugin-settings.
Where are these settings?
