I’m using the latest Chrome, but I get the same problem in the latest Firefox. If I change the headers in the two files (with the ones you have above, would that fix it?
I don’t have this problem on 3 other of my sites (on different servers), so this was surprising me.
Could it also be a server problem, that somehow when uploading, or extracting from the zip, it’s changing the type?
thanks for your help. I love the plug!!
