The allowedOrigins relates to postMessage message passing (e.g., between an 
embedded editor and the actual editor). Your issue appears to be that the fact 
you are hosting on https is not allowing you to grab to http, and that is no 
doubt a browser restriction that can't be overcome short of changing both 
servers (the one hosting SVG Edit and the one hosting the image) to http or to 
https.

i have reviewed this error more. there error thrown in this function 

canvg(c, data.svg, {renderCallback: function() {
    var datauri = data.quality ? c.toDataURL('image/' + dataURLType, data.quality) : c.toDataURL('image/' + dataURLType);
    exportWindow.location.href = datauri;
    var done = $.pref('export_notice_done');
         if (done !== 'all') {
        var note = uiStrings.notification.saveFromBrowser.replace('%s', type);

        // Check if there's issues
        if (issues.length) {
        var pre = '\n \u2022 ';
        note += ('\n\n' + uiStrings.notification.noteTheseIssues + pre + issues.join(pre));
        }

        // Note that this will also prevent the notice even though new issues may appear later.
        // May want to find a way to deal with that without annoying the user
        $.pref('export_notice_done', 'all');
        exportWindow.alert(note);
    }
}

Specificly on this line 
var datauri = data.quality ? c.toDataURL('image/' + dataURLType, data.quality) 
: c.toDataURL('image/' + dataURLType);

File Name svg-editor.js Line #: 1087
