Missing Menus

Gentlemen: I have your Catch Responsive Pro theme, version 4.3, installed on my podcasting site https://www.hablandodetecnologia.com. My latest renewal was on October 29, 2018. Yesterday I noticed something weird. My menus disappeared!!! I tried tinkering with the site, turning off this or that plugin but nothing worked. In the past months I also have made several changes to my site. First I changed from HTTP to HTTPS. Later on I changed from PHP 5.6 to PHP 7. The fact is that I have no idea what could be causing my menu to disappear. Can you please help?
