No need to respond to this post, as it’s just a work-around for anyone else who has customers moaning about the formatting of the Cornerstone menu as mentioned in this post by @Tech4Eleven - Cornerstone menu item missing from top bar after Wordpress 6.5 Update
Adding the following to functions.php of your child theme will add the necessary CSS to correct the formatting issue with the menu:
// Cornerstone Admin Bar Menu Item
// =============================================================================
add_action('wp_head', 'my_admin_custom_css');
add_action('admin_head', 'my_admin_custom_css');
function my_admin_custom_css() {
if ( is_admin_bar_showing() ) { ?>
<style>
#wp-admin-bar-tco-main .tco-admin-bar-logo.ab-item {
display: inline-block !important;
}
#wp-admin-bar-tco-main a.ab-item {
display: flex;
align-items: center;
}
</style>
<?php
}
}
