Impossible to do "Collect now"

Hello,
i would like to do “Collect now” in the screens menu, but i have a window say:

ZERO MQ iq required, check your configuration.

Could you help me please. This functionnality is very interesting to force screens when i want make tests.

Thx

Assuming that you have manual installation on a web server, then please see the following manual page for environment changes (and zeroMQ) - https://xibo.org.uk/manual/en/install_environment.html

Then look at the XTR (tasks) and XMR (push messaging) link on the left on that manual page.

Ok… It seem to be really complicated…

Thx for your help.
