At first: I browsed the 18 pages of this thread and I must say … Outstanding work!!! *bow* Thanks a lot.
I have a firefly server running and ITunes connects without any problems.
I copied the three files from the zip archive to the …/mt-daapd/admin-root folder. If I call the FirePlay.html on my WebBrowser, the Flash GUI (FirePlay v0.61) appears. I can see all the Text Boxes and the following message at the top of the page:
Connecting to http://MyServer:3689
And this is it. Nothing else happens.
