It's strange that this error popped up after the move
But yeah, it was probably broken before.
The old server has the files correct (that's where I patch in the current ones), there just must have been a hiccup when transferring stuff to GitHub. And since I used content from there, it's no surprise or strange that it would show up wrong after the moving.
I've no idea how you did transfer the stuff to GitHub, but besides the documentation issue, most of the attachments were missing as well, so something for sure didn't go 100% smooth.
