Category blank page

I understand you mean a category like /advert-category/auto-moto/, unfortunately this is a conflict between your theme and WPAdverts, there are two ways to fix it:

1. install the Alt Terms Links snippet https://github.com/simpliko/wpadverts-snippets/blob/master/alt-term-links/alt-term-links.php on your site, this is easy to do and should work with any site but has a slight SEO disadvantage.

How to install the snippet you can find out here https://github.com/simpliko/wpadverts-snippets at the bottom of the page.

2. create a taxonomy-advert_category.php template file to handle displaying the category pages as explained here https://wpadverts.com/documentation/child-themes-and-templates/ in Custom Taxonomy Template section.

Hi, i am not sure, can you email me a link to a page where you are having this issue?

I am not familiar with your theme so i cannot tell, maybe you will need to customize different part of the taxonomy-advert_category.php template.

If you are not familiar with PHP programming or WP development it would be better to use the solution #1.
