Error CS0150: A constant value is expectedNot An Issue
The official version of the plugin is compiling fine. This section is for support with the official version. Using the code you provided also works fine.
the code i posted is working fine for you is that what your saying Wulf?
Yes, after changing a character (which I assumed was a paste issue with encoding), no errors, and no errors on the line mentioned in your error.

Changed:
static char _formattingChar = '§';​

To:

static char _formattingChar = '§';

Dang i see now thanks Wulf!

Now this error :( Can you help me Wulf?

I would suggest contacting whoever made the custom version for you.
ok thanks was made a year ago or so., not sure if there around anymore :(
Hard to tell at first glance, would probably take a bit of trial and error and safety checks.
No worries Wulf i fixed it :D
