What theme are you using? Can you post a link to your site?
I’m using the “Make” theme. My website is http://www.usembassyjerusalem.com TIA
I’m sorry, but I can’t seem to reproduce your issue. Can you verify that the menus are still assigned to their appropriate locations (Dashboard > Appearance > Menus > Manage Locations)? Also, you might get better results if you post at your theme’s dedicated forum: https://wordpress.org/support/theme/make#new-post
When I get to manage locations I’m not offered any “selections” to choose from. Drop down menu is empty. Yes I will try the “Make” forum. Thank you Stephen!
