ProperTree not working on Catalina

ProperTree not working on <a class='btn-link text-<span class='badge badge-success'>Success</span>' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina</a>

I can not enter my config.plist, I can not put new kext or do absolutely nothing. The same goes for MountEFI
