I am using Extra theme by Elegantthemes for my wordpress site. On trying to access the Menu customization page, I received the error.
My apologies if this question is a little bit too childish but I am still an amateur when it comes to handling wordpress.
I presently do not know what could possibly be wrong and how to fix it
Kindly Help, Thank you
