So I've given up on the node.js debacle (godaddy is not my friend right now) and have switched gears to use the php version instead. I've got it working perfectly in Chrome, but get problems in IE when trying to save while NOT logged in.
When I go to save the page in IE, it tries to save the file locally (as expected), but gives an error saying "randomlonggeneratedlettersandnumbers.htm couldn't be downloaded" and there's no other information I can find about why.
So then I wondered if maybe TW-Receiver could help, but not only did it not solve the original problem, but now it pops up this message: "TW-Receiver error "Missing some user input parameters. Save Failed".
Again, as far as I can tell, this is just IE (since it won't get me do anything else there, I can't try logging in to see if that helps or not, so for right now all I can say for sure is that it's when the unauthenticated viewers try to save.
