Hi,
I recently purchased Premium and activated all customiser options. In Customiser the preview does not live update when changes are made. Also, there is a white space directly below the menu section that fills the entire preview window. ALso in the preview window, I get the following message at the top:
Notice: Trying to get property of non-object in /home/customer/www/exclusiveaesthetic.uk/public_html/wp-includes/nav-menu.php on line 825
