I figured out it has nothing to do with the older version of WordPress. I also fixed the jQuey, but the other problems remain.

So I was supposed to get mail if there were any replies, but didn’t get any…

Anyway, it turned out the problem was that I loaded Javascript through functions.php, and with that overwrote the Javascript for the slider. So it’s fixed now!

I’m running the website on localhost, so I can’t do that unless I add a screenshot or such.

I copypasted your code and then decided to replace $cat_name with the actual category_name, and that worked. This is exactly what I was trying to do in the first place, so thanks! 🙂

Actually, I thought I defined $cat_name in the first line of the code: figured the string of $cat_name would now be the category name I gave it. Apparently that’s not true, the output of var_dump gives me ‘null’.

I initially wrote this code with a post_id instead of category_name, but I’m making this for someone who needs to be able to make changes. Therefore, I need category_name rather than post_id. With post_id it worked like this, no errors whatsoever:

<?php
	$postid = 33;
	$content = get_post_field('post_content', $postid);
	$content = explode('|', $content);
		foreach ($content as &$zoekenNaar)	{
		$zoekenNaar = explode(':',$zoekenNaar);
			echo '<pre>';
			print_r($zoekenNaar);
			echo '</pre>';
		}
?>

I have tried just changing it like that, adding $category_name = 'zoekennaar', but it doesn’t work.

(I’ve added brackets to the foreach loop as you can see, forget that in the first place, and added print_r $zoekenNaar instead of $content now, which is what should be happening).

ADDED:

I created a new post to see what would happen. My code as it is now shows the most recent post, so $cat_name indeed doesn’t work. Figured most of you already know, but I’m not the only newbie so it might be useful for someone 🙂

I seem to have been able to fix the problem myself after all. It’s really simple (as I expected), just copypaste this code:

<?php recent = new WP_Query('page_id');
if ($recent->have_posts()) : $recent->query_posts(); ?>
	<h2>
		<?php the_title(); ?></a>
	</h2>
	<?php the_content(); ?>
	<?php else: " " ?>
	<?php endif; ?>

Most of this code came from here: https://wordpress.org/support/topic/how-to-display-a-specific-page?replies=3 , I made some small changes to make it work for me.
