Hello, @vidomarketing,
Thank you for providing us with your login details. Upon reviewing your site, we have discovered that there is no box shadow present below the sticky header when in customizer mode, and it appears to be functioning correctly. However, it does appear on the site’s front end.
We kindly request you to review the attached screenshot for your reference.
in customizer mode: https://postimg.cc/tspthXcP
On-site front-end: https://postimg.cc/ctd4FbGD
We suggest that you attempt to temporarily disable any caching (CDN) and cache plugins, Flush the server cache completely and clear the browser cache, and then check again.
If you are able to see the changes in the Customizer but not on the page front, it is likely a cache issue. If it is working correctly in the Customizer, it should also be working on the front end.
We hope this will solve your issue.
If you have any additional questions or concerns, please do not hesitate to reach out to us. Our support team is always available to assist you.
Best Regards,
8Theme’s Team.
