I just remembered that I secured the access to wp-admin folder with a .htpasswd file.
I have a question, why does your plugin need access to the wp-login.php?
Now I get the following error message:
XMLHttpRequest cannot load https://ssl.webpack.de/smokelowandslow.com/wp-login.php. No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘….com’ is therefore not allowed access.
My provider offers me a SSL-Proxy that I’m using for the backend login.
I guess the prevention of the domain mix is a security feature to protect the user. Do you know a solution for that problem? I guess it should have the same problem without a ssl-proxy. https and http mix should be prevented as well.
