Move category position

Hi,
you should be able to use a plugin like

https://ww.wp.xz.cn/plugins/wp-taxonomy-order/
https://ww.wp.xz.cn/plugins/simple-taxonomy-ordering/

to reorder the categories from the wp-admin / Classifieds / Categories panel, the order you will set in the wp-admin should be automatically reflected on the page with the [adverts_categories] shortcode.
