I’ve just noticed this within admin
ray() expects parameter 1 to be a valid callback, function ‘wp_site_icon’ not found or invalid function name in /home/sunonthe/public_html/wp-includes/plugin.php on line 496

Thanks, I will go back to the developer then. Hopefully he can shed some light on it.

Also when I try & update to 4.3 I get error coded 404 – Page not found
