Is this the same server, with the same operating system, with the same settings as you were accessing all those other times?

Red Hat / Fedora and others have added a standard feature in the last couple years that's being embraced more and more, called se_linux. This is a security watchdog that keeps a very close eye on any files/folders marked with 777 permissions, and snaps them back to defaults. It can be very handy for a webmaster, but can be intensely frustrating for a developer unless you know how to disable it.

You might want to raise the issue with your host, since you will encounter additional difficulties when uploading file images via the Zen Cart Admin interface, as well as some file-customization that is driven by the admin, thus requiring 777 permissions on some items.

You might point your host to this article, after reviewing it yourself, for a list of things to secure once installation and customization is largely complete. You host will likely be happy to know that you do all of these post-installation:
