SSL not working with company logo

Hello community,

does anyone else have the problem that having a company logo set in the settings the SSL certificate is not recognized anymore? The inspector of the browser say: "[Warning] The page at (URL) was allowed to display insecure content from (URL)/uploads/76. (URL), line 610)"

Deleting the company logo from the settings makes the SSL immediately appear again and everything's working as expected.

How can I fix this?

Best regards,
Jonas
