Undefined index: scheme error

Hi,

I’ve scanned the plugin files for an undefined variable $scheme, it’s used twice in the plugin functions, and it’s defined. So, it won’t cause this error.

Also in another check, the only place we are using a function that could cause this is here, but we check here for variable before using it!

See below:

if ( !empty($logo) ) {
			$logo_attachment_id = attachment_url_to_postid( $logo );
			// If the above function fails, we can use the commented one below:
			//$logo_attachment_id = schema_wp_get_attachment_id_from_url( $logo );
	 		if ( !empty($logo_attachment_id) ) {
	 			$schema['logo'] = schema_wp_get_image_object_by_attachment_id( $logo_attachment_id );
				$schema['logo']['@id'] = $url . '#logo'; 
	 		} else {
				// It's external, use image url only
				$schema['logo'] = $logo;
			}
	 	}

I think this is coming from somewhere else, and not caused by the Schema plugin.

Thanks for digging more into it.

Have you set the logo in: Schema Settings > Knowledge Graph > Organization info?

This probably where the function would trigger an error.

I will do another test to see what comes out and let you know.

I am asking because the notice you are seeing in the logs may comes from the function that returns logo image details.
