You are limiting your resource access to only http://mabbo.biz/ but accessing the resource from https://mabbo.biz/ , the two schemes don't match hence the CORS error, http and https are different.

Also, your wildcard * is being overwritten by your explicit one, or as MDN puts it.

Access-Control-Allow-Origin specifies either a single origin, which tells browsers to allow that origin to access the resource; or else — for requests without credentials — the "*" wildcard, to tell browsers to allow any origin to access the resource.

So since you have the http://mabbo.biz/ origin specified, any other origin will be rejected.

You could add a check to allow wildcard's on specific URLs or specific resource types, like .jpg|.png|.gif .

How that will be accomplished will differ from server to server though, so you'll have to look up how your server handles that check.
