I haven't had any issues with the domain mapping plugin up until now. For some reason, the images have started triggering a 404. They are fine at the original URL (wayofbeauty.thomasmorecollege.edu), but they are broken on the front end, where the domain mapping is presumably applied (thewayofbeauty.org).
If you look at the site, you can see that the last two posts have broken images, but all other posts before that are fine:
Any idea what might be going on here?
