Trying to push categories of events to 'child' sites in multisite


I’m trying to have a ‘Master’ events calendar in a Multisite environment which displays events in a certain category on ‘child’ sites.

I am exploring doing this with RSS, but I noticed that with the Post Indexer you can share things between sites to a certain extent.

Is it possible to accomplish what I am trying to do? I have successfully made the calendar show up using [eab_calendar network=”yes”],

but I get an error (below) when I try [eab_archive network=”yes”], which would allow me to define a category.

The error I receive is:

Fatal error: Call to undefined method WP_Post::get_id() in /var/www/taija/wp-content/plugins/events-and-bookings/lib/class_eab_template.php on line 617
