MyBB Community Forums - Help! Theme/CSS not working when logged out

The theme of my myBB website is not loading, and instead has an ugly "pre CSS" look.
http://sharktacos.com/Forums/

also http://docs.sharktacos.com/

This was working fine, and then yesterday it suddenly broke. I have not changed anything on my side.

One thing I observe is that if I am not logged in, the formatting/theme looks fine, but when I'm logged out it loses the formatting/theme.

Any help appreciated!

Note that the problem appears to be intermittent. Was not working all day... came home and it seemed to be working again (i.e. correct CSS/theme formatting), then later in the evening not working again.

Weird.

there is some problem with cache of the stylesheets (esp. global.css)
would you like to PM me temporary access to forum admin panel & files (FTP) to check it ..

I sent you a PM

Is there a way to have it point to a different style sheet that is not cached?
there's really no reason it needs to be cached since I never change it. So that might be an easy fix.

For example: would it be possible to point the pages to this CSS static stylesheet:
