Problem after update

After that i update Illdy Theme to 2.0.4 i didn’t be able to costumize anymore the theme. When I go to costumize section there is only the widget option but i can’t enter to it. There is no preview of the site because all stay gray.
The other things that i see is that colorlib is social and the link to the documention that sent me here.

Can you help me?

Hello there,

I hope you are doing well today.

Please disable any third party plugins that you have active then try accessing the customizer once more. Also, contact your hosting provider and ensure that you are using PHP version 5.6 or higher.

As a follow up, I update the theme as well and everything still works on my site except the % signs don’t show up anymore.

Can you please clarify what I need to do.
