Hi,
Everything works as it should.
After I activated the Agama Pro theme, there was a notice that you need to activate the necessary plugins.

Then I installed and activated Plugins for you.

You should now register your theme.
After that, you will receive a notification that there is an update on the theme.
If you want, you can migrate your site
If you need any help please feel free to contact us.
P.S I noticed that you are using too many plugins on your site. Having too many activated plugins is a good recipe for the disaster, so I suggest you to deactivate the plugins that you are not using.
Regards
