2 days ago I decided to add colours and change my pe name, I searched up a youtube video to show me how (by holding 's' with 'c' through it button. I got a new name with colours. I go to do multiplayer but it says invalid name. I can longer type anything in the name box - no new name and neither my old name. So I can no longer play multiplayer. I also posted this query under another bug file loaded by 'Rilow06' who looks like they had a similar issue.
Can you let me know how to fix this please.
Thank you Peter

btw: the version I have is 0.11.1 but the box above didn't allow me to select it
