Could not pass event AsyncPlayerChatEvent to bChatManager v3.1.1

When trying to send a message in the client the following errors appears and normal MC message is used instead of bchatmanager.

Using the console of the server works alright.

Using Mcpc+ with FTB Direwold20 (1.6.4) with bchatmanager 3.1.1
