Hi @techgil

Add the following code to your theme’s functions.php file:

if ( is_plugin_active('simple-side-tab/simple_side_tab.php') ) {

	add_action('wp_footer', 'rum_add_birdseed_class_to_sst', 999);
	function rum_add_birdseed_class_to_sst() {
	echo '<script>document.getElementById("rum_sst_tab").classList.add("birdseed-link");</script>';
	}
	
}

That should add the birdseed-link class name to the tab.

I was seeing the same error message. It does appear that there is an issue between this plugin and Yoast. Our submissions stopped after the Yoast 15.8 update. Downgrading to 15.7 works for now.
