it simply looks like your tour.xml is not found
check your index.hml if it really points to your tour.xml
if yes, check the permissions on your tour.xml

Thanks for the feedback. The tour works fine offline. In fact, it used to be online on my old website. Nothing has been changed. I can run it using the KP testing server. The tour.html is properly pointed to the correct .xml file.
UPDATE:
As I have 2 different hosting accounts, I went ahead and uploaded the tour to another server and it works fine. Both of my accounts are with the same host, FastComet, and in the same region (Singapore). So I find it very hard to understand why one specific server is preventing it, while another is allowing it to run. I uploaded and tested it with a few variations on the problem server and all failed. The same files worked fine on my other server. I will take the matter up with my host.
