Hello Ariel,
Thank you for purchasing our theme and for reaching out to our support center.
We have reviewed your website and determined that the issue is likely due to a CDN being enabled on your site. https://postimg.cc/7C965JRF
If the changes you have made in the Customizer are not visible on the front page, it is likely a cache issue. If the changes are visible in the Customizer, they should also be visible on the front end.
We recommend that you try temporarily disabling any CDN caching or cache plugins, and clearing the browser cache, and then checking again. We have also provided a video for you on your site under the private content area for further reference.
We hope this resolves your issue.
Best Regards,
8Theme’s Team
