Hi, i found some incompatibility. When ChatPlus enabled on my fabric server, chat messages not sends to Dynmap (browser), but messages from Dynmap (browser) to game works good.

versions:
minecraft fabric 1.20.4
chat-plus 0.20.2-mc1.20.4
dynmap 3.7-SNAPSHOT

In logs there is no errors, warn or info.

Can you check, where problem can be? This is definitely related to this mod

Thank you for raising this issue!
I'll try to address it as soon as possible

The issue has been addressed.
A new version was updated and released.

Thank you!
