What's happening is that if a relative path is detected in a markdown url, this code checks that the relative path prefix is there. I'm not really sure why this is the case. If I'm running Wordpres (I am) and upload images there, shouldn't I be able to use relative URLs without enforcing the relative_path?
@julian, I think I fixed this issue. I rolled back to a snapshot before I installed NodeBB and re-cloned the 0.5.1 branch and it installed without an issue and I have sweet, glorious CSS!
