Ofmeet plugin not working

I have installed the Ofmeet plugin(s) (Openfire meetings and focus provider) but it does not appear in the admin console. https://xxxxxx:7443/ofmeet/ says “error 404 not found”.
I tried reinstalling openfire also as just restarting it. Both did not help

Do not install the offocus plugin. It is incompatible and unneeded with ofmeet 0.9.5 and later.
