If your 111 website generates a "403: Forbidden" error

Any .html file you upload to your 111 folder on the server must be "world readable," otherwise a 403 error results ("Forbidden: You don't have permission to access") when you try to open the file in a browser.

Permissions are usually set correctly by default but, sometimes, a permission gets changed during the upload. Then you will have to set the file's access mode explicitly.

Here's how to DIY (Do It Yourself):

Using either SSH (Windows) or Cyberduck (OS X), you can select the file on the server and list its Properties. "Read" permission needs to be enabled for "Other".
