Problem changing page configuration live preview do not work

Hello good night, not if you can support me I write because I have installed Graphene theme in WP on my site, but I have problems to customize it. When I go to “Appearance> Customize”, the page does not load, the part where you should see the live preview is blank and the options on the left do not work.
This updated all in all 3 sites have the same issue and the problem appears on 2 and 1 everything works fine.
