I got an email from WP saying there is a fatal error on my site. The error is detected on the page http://ugen.ca/wp-admin/nav-menus.php. The website host suspects that the problem is related to the website scripts compatibility issues. The Menu on the Appearance tab on WP does not open properly. Is there a solution?
Here are the error details:
