User ranks divided by '/' plugin I requested not working in 3.8

[LostForWords]

Firstly I'll refer you to this thread, which is me requesting a plugin to prevent user ranks entering a new line and (basically replacing the <br /> with '/').

This worked wonderfully when I was using 3.7 but I'm working with 3.8 software at the moment and it isn't working so well. It has successfully prevented the user ranks entering separate lines but unfortunately they aren't being divided by the '/' symbol I'd like.

Could anybody be kind enough to help me make a quick fix to this to ensure it works correctly?
