Menu not displaying

I don’t know what happened, but some days back I started seeing this warning that said - Warning: Illegal string offset ‘nav_menu_locations’ in /home/content/n3pnexwpnas02_data03/76/3459876/html/wp-includes/theme.php on line 905. I am using Travelify

I have tried everything that I could have from forums and myself, but everything in vain. During the live preview everything works fine, but as soon as I publish it, the menu won’t display anything.

I have also tried deactivating all plugins but it is the same. Can you please help me?


Please provide us your website link, a temporary admin pass and user in a private message.

Thank you,
