True, but the baffling part is that — as long as I change the name of the index page to “index.html” after publishing it from RW — the page and all of the stacks on it are fully functional when hosted on AWS S3, which does not support any form of php. So other than a serious case of embafflement over why things work when they shouldn’t, my problem isn’t really a problem. In a related thread, Joe Workman suggested that gremlins were the probable cause of a similar problem, and at the moment, that’s the only explanation that seems to fit.
