XHR request for configurationjs fails due to CORS policy

Change https://www.wiris.net/demo/plugins/app/configurationjs to allow any origin.

Is unfortunately not an option as we have no control over that.

I just tested this on a live site and there it still seems to be working fine. Can you share some more info like error logs for example?

I have moved configurationjs to variable to try to fix Cross origin issue with configurationjs, but after that I got another Cross issue with generating image url (see attached screenshot)
