ViaChatFixer is a Spigot plugin that allow 1.11+ players to have longer chat messages on 1.8-1.10 servers with ViaVersion
In Minecraft 1.11, the maximum messages length has gone from 100 characters to 256 characters. So if your server is under 1.11, 1.11 and higher players will have their chat messages cut at 100 characters.
This plugin fix this problem, so 1.11 and higher players will be able to send longer chat messages up to 256 characters.
You can download releases and find more information on SpigotMC.
Just put the ViaChatFixer jar in your plugins folder.
ViaChatFixer currently supports ViaVersion v3.0 or higher.
All players online during a reload will not be able to have longer chat messages until they reconnect.
ViaChatFixer can be installed on Bukkit/Spigot/Paper servers or on Sponge servers.
If you are using a proxy, ViaVersion and ViaChatFixer must be installed on the backend servers.
