Hello,
Hello, @Santi,
Sorry for the inconvenience but I have checked your site now and found that the Cache plugin (WP-Optimize – Clean, Compress, Cache) causing the issue on your site. I just deactivate that plugin and your issue is resolved now. Please check back to your site after clearing the browser cache. I have captured a video for you on your site. Please watch it completely for a better reference under the private content area.
Regards 8Themes Team.
