So this is the template for wordpress. https://themeforest.net/item/knowledge-base-helpdesk-wiki-faq-wordpress-theme/3434096 On the webserver i use MariaDB 10.5. The problem is, i've never done something with php. Only with html, css. I added categories in the wordpress backend but im not sure where this error comes from, or how i can fix that. 😕

I've got 2 error messages after I set up a new wordpress installation & installed the knowledge template. It's the first time for me to setup a wordpress page & template. I'm not that known in php and i didn't find a solution for this. So here u can see the error messages live: https://www.kassen.de/knowledge/knowledge-base/ The Errormessages are: Warning: count(): Parameter must be an array or an object that implements Countable in /homepages/37/d157950258/htdocs/knowledge/wp-content/themes/knowledgepress/template-knowledgebase.php on line 98 and Warning: count(): Parameter must be an array or an object that implements Countable in /homepages/37/d157950258/htdocs/knowledge/wp-content/themes/knowledgepress/template-knowledgebase.php on line 116 And this is the code from the php files on the specific lines: Line98: if(count($subcategories)==0 && count($cat_posts)==0){ continue; } Line 116: if(count($subcategories)>0) { foreach($subcategories as $sub_category) { $term_id[] = $sub_category->term_id; ?> Does someone has a solution for this? This would be awesome! Greetings :)
