I can't seem to solve this issue.
Here's the registration of the connection:
When I am in the edit screen for the case study post type, and connect the endorsement, that works and makes the following record in the p2p table:
from: case study ID
to: endorsement ID
And the query parameters used to attempt to retrieve the connected endorsement are:
Array ( [post_type] => endorsement [orderby] => menu_order [numberposts] => 1 [order] => ASC [post_status] => publish [connected_type] => case-study_to_endorsement )
But the result is:
Warning: Could not find direction(s). in /home/*****/wp-content/plugins/posts-to-posts/core/query-post.php on line 16
Any advice would be greatly appreciated, thanks.
