Please update to the latest build, then post the full output of /ess version.

[Dolphin2Point1]

@dariasc I added the log.
@md678685 It only says "Essentials reloaded 2.0.1-b601."
I'll try updating my build.
Update: @md678685 The new build worked! Chat Issue persists tho

What do your Factions titles look like?

[Dolphin2Point1]

There isn't any, there is just the default
But it wasn't happening before the factions tag either
And anyway factions works so that someone with no faction is part of the wilderness
Can some one help me?

[mdcfe]

If this is still an issue, are you using a plugin to inject placeholders into the chat format? EssentialsX Chat currently doesn't support PlaceholderAPI.

[Dolphin2Point1]

Oh. PLS FIX. Actually, you don't have to right now. But pls fix.
Edit: That is a yes.

[mdcfe]

@loper12 Could you answer the question I asked above?

are you using a plugin to inject placeholders into the chat format?

[HotProtato]

I had this same error when I tried using AsyncPlayerChatEvent#setFormat as well...

[mdcfe]

@MajorSkillage Are you using a placeholder injection plugin?
@loper12 I can't help unless you answer the question.

[HotProtato]

@md678685 Yeah. I just tried replacing %tag% as a string in my plugin after adding %tag% into essentialschat format, it didn't replace it and just gave an exception. Could it possibly be because in the plugin the two placeholders being used for the username and the message don't get replaced first causing the exception to occur whenever a "%" is used? It's what I'm thinking anyhow, note that the EventPriority was set to LOWEST in my plugin.
