Getting Warning: Missing argument 3 for gss_gallery_sc_filter()

I am also getting “Missing argument 3 for gss_gallery_sc_filter()”. On all pages with a gallery. Using GSS or not.

To fix this, you just need to set the third arg ($instanc) equal to ”. Like so:

On line 72 of gallery-slideshow.php file located in the plugins root change the function to the below:

gss_gallery_sc_filter($output = '', $atts, $instance = '')

So the full function would look like this:

function gss_gallery_sc_filter( $output = '', $atts, $instance = '' ) {
	$return = $output; // fallback
	
	if( !empty($atts['gss']) ){

		// retrieve content of your own gallery function
		$gss_output = gallery_ss::gss_shortcode($atts);
	
		if( !empty( $gss_output ) ) {
			$return = $gss_output;
		}
	
	}

	return $return;
}
