Customizer is not working

Hi
I just bought the Alizee Pro theme, I installed the theme and it is ok. However when I try to customize the thme (logo, color, and so on), the customizer is not working and IT IS VERY SLOW.

The rest of my blog is Ok.

Please let me know what to do

Thanks

Hi,

Please try to deactivate all your plugins and check then how it works.
