Hello,
Sorry for the delay in answering.
When opening your logo image http://www.globaldefense.us/wp-uploads/2021/09/global-defense-png.png in any browser it redirects to Home page, but all is fine with others, for example, https://www.globaldefense.us/wp-uploads/2021/07/international-sales-representation-and-marketing.png
Do you have something written in .htaccess that may cause it?
Try to upload a completely different image for the logo and check how it works then.
Regards
