Sorry Klaus,
I have (I guess) a similar problem which is addressed many times before. However I can't seem figure it out. I created this tour today and it works fine. -> http://www.mousemedia.nl/panoramas/EmiratesHills/tour.html by default I believe it runs in flash.
However when trying to load it on a iOS (or any HTML5 machine I get FATAL ERROR: tour.xml - xml parsing failed!
If I try to address the xml -> http://www.mousemedia.nl/panoramas/EmiratesHills/tour.xml I get an error on my computer
if I try to add the parameters -> tour.xml&html5=prefer it can't find the file?
I reuploaded the original xml files the create tour droplet onto the server without success. :(
an exact copy from the xml is dumped here so you can have a look at it. http://www.mousemedia.nl/panoramas/EmiratesHills/tour.txt
Please advise.
I appreciate your support.
