Im having the same issues and have followed all of your steps @rodicaelena but I am still getting issues with the front page. It looks like the big title for the Testimonials section as well as the icons for address/email/phone # in the footer are not showing up unless I am logged in to the wp-admin and in the customizer.
I too am having issues. The testimonials header title will not display unless I am logged in and editing the customizer. Same for the small icons in the footer for address/email/phone number. I have all of the themes and plugins updated but still getting inconsistent results.
