I am truly sorry that I read your message this late, but I was busy these past few days.
 
Your chat changed because before it did not use HTTPS (secure) connection and the userstyle was still linked to the HTTP chat. Here's the fixed version: https://userstyles.org/styles/107653/mlgslayer-chat
 
I hope you did not go crazy in the meantime, and apologies again for not helping earlier
