In your social icons file

<?php if ( 'on' === et_get_option( 'divi_show_linkedin_icon', 'on' ) ) : ?>
	<li class="et-social-icon et-social-linkedin">
		<a href="<?php echo esc_url( et_get_option( 'divi_linkedin_url', '#' ) ); ?>" class="icon">
			<span><?php esc_html_e( 'Linked In', 'Divi' ); ?></span>
		</a>
	</li>
<?php endif; ?>

<?php if ( 'on' === et_get_option( 'divi_show_youtube_icon', 'on' ) ) : ?>
	<li class="et-social-icon et-social-youtube">
		<a href="<?php echo esc_url( et_get_option( 'divi_youtube_url', '#' ) ); ?>" class="icon">
			<span><?php esc_html_e( 'Youtube', 'Divi' ); ?></span>
		</a>
	</li>
<?php endif; ?>

For "multiple times" issue just change "require_once" to "require".

For newer Divi versions, you can change divi_show_google_icon to divi_show_instagram_icon and divi_google_url to divi_instagram_url

Hello @mrkdevelopment , Is it possible to clarify the licensing of the code?

Its GPL - you can do what ever you want with it.

Thanks Rameyrobo. BTW - we have a free plugin now that handles all of this which may interest readers.https://www.mrkwp.com/wp/divi-icon-toolkit/

FYI, that URL doesn't resolve, searched your site and couldn't find the toolkit either.

@ExponentiallyDigital I no longer have the plugin. The code is here as a GPL snippet but I have no idea if it still works. You may find some alternatives on the divi marketplace.
