Hi autohimarius,
I struggled with removing the tooltips, tried altering the menu attributes as well as. a plugin. No success.
What finally worked for me is creating a child theme, then adding this code to the new functions.php file located in: public_html or www / subfolder if you use one /wp-content/themes/vega-child
code:
<?php
add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' );
function my_theme_enqueue_styles() {
wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
}
function my_menu_notitle( $menu ){
return $menu = preg_replace('/ title=\"(.*?)\"/', '', $menu );
}
add_filter( 'wp_nav_menu', 'my_menu_notitle' );
add_filter( 'wp_page_menu', 'my_menu_notitle' );
add_filter( 'wp_list_categories', 'my_menu_notitle' );
?>
