describes how to register a taxonomy.
When I try to access groups as a taxonomy, it does not seem to be registered.
For example, when I have used https://en-ca.wordpress.org/plugins/related-posts-by-taxonomy/
the posts that have similar groups do not appear.
Can someone help and advise me on this please?
Thanks in advance
Although i’ve never tried to use groups as taxonomy, if i wanted to organize posts based on restriction groups, i would first get a list of the post ids and for each post id i would fetch the post_meta.
