Share Preview Image

Hello,

You don’t see the image because WPMM uses a custom template for the maintenance mode page, and the SEO plugins have no idea about how to embed the image in that custom template.

The only way to add a social preview image is to add the meta tags programmatically.

Disclaimer: do not try if you are just a basic WordPress user.

add_filter('wpmm_status_code', function($http_code) {
	if(!empty($_SERVER['HTTP_USER_AGENT']) && stristr($_SERVER['HTTP_USER_AGENT'], 'twitterbot')) {
		return 200;
	}
	
	return $http_code;
}, 10, 1);

// you have to change twitter:title and twitter:image values
add_action('wpmm_head', function() {
    print('<meta name="twitter:card" content="summary_large_image" />');
    printf('<meta name="twitter:title" content="%s" />', esc_attr('here should be a title'));
    printf('<meta name="twitter:image" content="%s" />', esc_url('here should be the url of the social preview image'));
}, 10, 1);

Add the code to the end of functions.php (a file that can be found in your active theme folder).
