Archieve Tile

Option 1: with your own code that you add to your plugin, the functions.php of your child theme or via code snippet plugin:

add_filter( 'get_the_archive_title_prefix', '__return_empty_string' );

Option 2: use this plugin:
https://ww.wp.xz.cn/plugins/wp-remove-category-from-archive-title/ (it’s relatively new, I haven’t tested it yet).

Possibility 3: SEO plugins like Yoast or RankMath offer an option for this. Contact their support if you already use one of them.
