What is this error Why cant i send chat?

This happened to me on Skyblock yesterday.

 

Can't remember exactly, but it's somewhere in the multiplayer settings.

 

Can you not just relog to fix this issue?

 

Go into multiplayer settings and check if you have the function Chat:Command Only or Chat:Hidden on. Just change that to Chat:Shown if that is the problem.

 

Yes, the only cause I am aware of for that error is if you disabled chat in your client's multiplayer settings. If you follow the above advice it will resolve your issue, just change it back to Chat:Shown and you will be fine.

 

Has this caused any other problems?

 

If the previous solutions don't work, delete your current minecraft and re-download it.

 

I, unfortunately have no idea what else do to.

 

Sometimes I lag so bad till I get kicked out.

 

Yeah, you may want to restart your router.

 

Oh yeah, I found a dent in my router yesterday but it wasn't related to it. Guess I'll just have to scoot over to challenger to get a new router...

 

Sorry about that, yeah you may have to.

 

Nothing to be sorry about, it isn't your fault anyway. Bye, going to buy a router.

 

Lol, glad to hear it.

 

It also sometimes happens when you're lagging and send a message right when you die.

 

I know what causes this. If you have such thing in your "Modified Client" called Lagger or something along the lines of that, turn it off, or if you are legitimately lagging try to speed up your internet. Disconnect any devices which aren't in use of the internet and close other programs using internet.

If you lag and then die and try to send a chat message you will get the same Popup. To test this out yourself, stand in the middle of a game and open chat then when you get killed try to type something. You will get that Popup/message.

Hope this helped.
