Map not showing on a Mac: Firefox & Safari Archived · read-only

My map is not rendering when I view it in Safari or in Firefox on a Mac. It worked fine in the past with a different map. Huh
What am I missing? Does it work for you?

the site is slowly dying by its own because the creator has left and the rendering and uploads do not work anymore.
