It looks like the host pushed an update that broke the .htaccess file. I can’t fix it myself, so they’ve created a ticket and I am waiting on someone with expertise to fix it for me. I have no idea when a technician will become available. Right now, all of the subsites are down (TOR Fashion is a separate site from the rest and is working).
EDIT: I called the host again this morning and the tech was able to reset the .htaccess file and the sites are working again.
