Okay it looks like I was using this old function to change the filter button text:
remove_action( 'init', 'woodmart_show_sidebar_btn' );
function woodmart_show_sidebar_btn() {
?>
<div class="woodmart-show-sidebar-btn">
<span class="woodmart-side-bar-icon"></span>
<span><?php esc_html_e('Show Filters', 'woodmart'); ?></span>
</div>
<?php
}
add_action( 'woocommerce_before_shop_loop', 'woodmart_show_sidebar_btn', 25 );
I removed this from my child theme and now the filter button says “Show Sidebar”. How can I change this button text now?
