 * Hi,
 * I’m sure it’s a great plugin.
 * But i can’t use it. After I’ve installed it. I’ve tried to access to “Appareance-
   > Menu” and WP has given me back this error message “Fatal error: Cannot declare
   class Extra_Walker_Nav_Menu_Edit, because the name is already in use in /home/
   koruai83/public_html/giovannamoon/wp-content/themes/Extra/includes/admin/admin.
   php on line 1758”
    I can understand that the theme or other plugin is using the
   same class name. How can i solve it?
 * Thanks
