Afternoon (at least my time it is..)

I've tried setting up this plugin using the Advanced Config and after setting it up, I'm getting error messages that aren't exactly clear to me.

I'm literally so confused as to this. I've tried v3.7.3 but now running 3.7.2.

Thanks in advance!

Not sure if this works but bump?

In case you haven't solved this issue, this error message tells you exactly what the problem is:

[11:15:25] [Server thread/WARN]: org.bukkit.configuration.InvalidConfigurationException: while scanning for the next token found character '\t(TAB)' that cannot start any token. (Do not use \t(TAB) for indentation) in 'string', line 64, column 62:

Do not use TAB when setting up your config and settings. Always use spaces. This is true for most plugins so better check your spacing if it's using a TAB or actual SPACES.
