haha, yes it did! no error!
what did you do? :O

I use 6 meta boxes for a custom post type I made, called ‘videos’.

They only contain short texts, which are actually URLs to different
content, that I then present depending on if a user is signed in or not, using a plugin called S2Members.

So there is nothing fancy about the content, just simple strings.

Hm, I had to google wp_debug, but then I found it in wp-config.php. It seems to be off already?

define('WP_DEBUG', false);

Can I turn the specific warning off manually somehow?

This is row 100.

if(is_array($val['__force_post']) && isset($val['__force_post']) && $val['__force_post'] == 1) { //be sure it's an array, or beware unsetting strings

I use the thumbnail template, if that helps. ??

I just installed the plugin locally, so it should be the newest. ?? I haven’t used it before, so I can’t comment on older versions, unfortunately.

If I put the related_posts() directly after the_content() I get the same result (“No results”), just displayed at another position. Nothing else seems to change.

The weird thing to me is it works fine if I use the auto display, but not the manual one inside my theme, in single.php. I was thinking perhaps there is some parameter missing?

Is the code when inserted automatically identical to the manual inserted one in the plugin?

The only reason I insert it manually is because I want it displayed at another position with some other stuff in-between my the_content() and related_posts().
