Have you got a plugin that has a /tell command, or a plugin that blocks commands or plugin lists?

Yes (about /tELL)
Yes, but /tOWN not works after update Towny

It is very unlikely that Towny is the cause of the issue.

Thx for help.
CoffeeProtect by default block command what start with "to".
I remove it and all working.
Sorry for waste time.
