You have an explanation/tutorial, that doesn't fit to my problem. See on this site: https://www.cleoco.at/ What I already found out is, that it has something to do with SSL - If I take the http:// url for the logo the warning is gone, but my page is not secure anymore - of course... So what happened in the last 3 weeks to get this error out of the blue and what can I do to resolve the issue. Thanks for helping me.
