Not sure what happened here, but I believe it had something to do with the /tmp folder permissions.

I found this source that suggested you can simply make the /tmp folder, just as you would any other folder, and then do a chmod 1777 on the newly created folder.

So, instead of deleting my current /tmp, I ran this chmod command and everything appeared to work.

What is strange to me is that I had previously done a chmod 777 and that caused the folder to not work. Weird...
