i think the CORS error should be easy to fix.... you guys can figure that out... although it looks easy enough to try and remove the www from both definitions in the configure file.
that HOWEVER is not the problem you are posting about. if you look at the console using developer tools you have the CORS error in both places; and yet one url the slider works, and the other url, the slider does not.
it is ENTIRELY possible that by removing the www and hopefully addressing the CORS error, the slider may work.... although i'm not sure why that world work....
as i previously stated, debugging jquery can be tricky, especially if you have limited experience...
here is the jquery error/loop....
best.
