Satellite wont load after manually installed gem virt_who_configure plugin

Hello everyone
After I manually installed virt_who_configure in my Satellite, my web page wont load, it says: " ERF72-3232 [Foreman::PluginRequirementError]: foreman_virt_who_configure plugin requires Satellite >= 1.20 but current is 1.18.0.40 (Foreman::PluginRequirementError) /usr/share/foreman/app/registries/foreman/plugin.rb:177:in `requires_foreman’"

The procedure I made was:
"gem install --ignore-dependencies foreman_virt_who_configure-0.3.2.gem
Successfully installed foreman_virt_who_configure-0.3.2

I have tried to uninstall gem with these commands:
“gem uninstall --ignore-dependencies foreman_virt_who_configure -v 0.3.2”

But no success!

If I execute: gem list foreman_virt_who_configure nothing appears, but if I execute: gem list foreman, it only appear:
“*** LOCAL GEMS ***
foreman_maintain (0.2.11)”

I have a Red Hat satellite 6.4 installed with RHEL 7.6 release

All the help is appreciated, thanks in advance
