Upgrading to 1.8.11 but stuck with ZeroMQ

Hello. I’m a newbie (very new) with Xibo. And I know the basic programming a little bit.
I’ve tried to upgrade version from 1.7.9 to 1.8.11 and still stuck with ZeroMQ installation.
I read the guide in Xibo website and search a lot before ask here… still not understand.
Could anyone guide me more by very easy and simple way to understand how to install ZeroMQ please?
I’ve took over Xibo CMS that was not used for awhile.
Nobody here can guide me. I need to learn by myself.

Thank you so much.

Since you have a /web in your CMS URL, that implies configuration error, as such please look at the DocumentRoot and URL rewriting sections in the URL above as well.

ZeroMQ and XMR configuration can be done after you install the CMS, however the DocumentRoot and URL rewriting should be set correctly before you start installation.
