Can't see anything in "Customize" inside the "Appearance" menu

[andrea]

As you can see from the screenshot below, when I go on the Appearance menu and then I chose Customize, I can't see the usual menu (Favicon, Menu Style, Site Title, Project Thumbnails etc..).
I tried with Chrome, Safari and Opera: the problem persists.

Do any of you know how to solve this?
Thank you in advance,

Andrea

Dear,

is LayTheme and Wordpress updated?
Which plugins do you use?

Best!
