Hi M,
You can change it under Share icons –> Miscellaneous tab. You can delete the “heading text”
Also, I see that there is no gap between the footer and the icons in your website.
You can use the below CSS in WP Socializer –> Settings –> Additional CSS if required.
.wp-socializer.wpsr-share-icons:last-child {
margin-bottom: 2em;
}
Thanks,
Aakash
