Solved config parse error

I'm back again with one of my stupid errors. I am trying to make a broadcaster plugin for my new server(opening soon) but the config won't load.
Error:

Code:

[19:10:51] [Server thread/WARNING]: RuntimeException: "yaml_parse(): reading error encountered during parsing: invalid leading UTF-8 octet (line 1, column 1)" (E_WARNING) in "/src/pocketmine/plugin/PluginBase" at line 261

Config:

Code:

#time it takes to broadcast a message in seconds
broadcast_time: 25
#messages to broadcast
messages:
    - "Thanks for playing on the BeastHub-NET server!"
    - "Have questions? My kik: \n§bAsk me there!"
    - "We are looking for staff, kik me at: "

I don't wanna show my kik here.

I solved it. I forgot to delete the old config file and it was crashing.
