Map goes into queue, but doesn't render

Hello, I'm trying to upload a map of the server I run. Everything goes smoothly until I hit save, at which point the map goes into the rendering queue, then instantly leaves the queue, having not been rendered. All I see if a blank white screen when trying to view the world. Could someone please take a look at the archive and see if it was set up wrong or something? I'm at a bit of a loss as to what might be the issue here.

I am sorry to inform you that our server does not support many mods, and most modding support is very dated.

Our render servers support the following modpacks:
Tekkit Lite 0.5.7
Tekkit Classic 3.1.x
Hack/Mine 0.6.4.2

There may be more modding support in the future, but for now that is all we offer. Sorry for the inconvenience.
