So I have very little php experience, and I would like to have posts that are in a similar category to be shown when clicking on the "<< Next Post" or "Prev Post >>" links.
I looked up how and found the function for
next_post_link() and it's parameters. So I went through my
publichtml/wp-includes/link-template.php file and changed the variable
$in_same_tax from false to true.
I also went ahead and changed all the instances (14 of them) where
$in_same_tax was set to false and changed them all too true as well.
I uploaded the new file via cpanel, and reloaded the page to test if this worked. It didn't.
I looked at other similar questions like this one. But all the suggestions that I saw either didn't work or didn't seem to apply to my issue.
I'm using a Astra as the theme if that matters.
Any help would be appreciated.
