Hi,
It’s because the search plugin is actually included within each post as the post content, see: https://i.imgur.com/zOYm0Ti.png
I am not sure if that is possible to remove, as it is within the post content, and the excerpt is automatically generated on those pages. Maybe via a custom code, but I am not sure if that does anything.
Try add this custom code to the functions.php in your theme/child theme directory. Before editing, please make sure to have a full site back-up just in case!
add_action('wp_head', 'asp_shortcode_unset_archive');
function asp_shortcode_unset_archive() {
if ( is_archive() ) {
add_shortcode('wd_asp', 'asp_empty_sc');
add_shortcode('wpdreams_ajaxsearchpro', 'asp_empty_sc');
}
}
function asp_empty_sc() {
return '';
}
