I might have spotted the bug.
As the title says when single-department.php is loaded and number of faculty is output as its related post, although there are more than 5 (faculty), the number of faculty is always displaying 5 only.
I tried to identify the file responsible for this (5) number output by filtering “post_count => 5” then I could only find “template > loop-post-list.php” which has the post count of 5. However changing the value to something like 9 (anything above 5) doesn’t seem to change anything. So I just suspect this is a bug. I am only assuming though this loop-post-list.php doesn’t seem like it is even used in the theme…
At the same time I noticed “template > singular > related-post > loop-custom.php is used to output this department related post (faculty) however me putting “post_count” there doesn’t change that only 5 faculty posts….
It would be great if you could look into this.
