The mod disables translations into other languages. If I delete ForgeEssentials, the rest of the mods start writing messages in the right language in the chat, if you return ForgeEssentials then the messages are only in English. Is there any way to fix this?

Please Clarify what version of Minecraft you are using?

1.12.2

The file modlist.txt can be found in your ./forgeesentials folder. Just upload it to gist or pastebin.

Try disabling the Chat module in main.cfg

This hopefully will stop the translations from being removed and will narrow down the translation issue to the Chat module.

Here are the modules that I have included
Modules {
B:Afterlife=false
B:AuthLogin=false
B:Backups=true
B:Chat=false
B:Commands=true
B:Economy=false
B:Multiworld=true
B:PlayerLogger=true
B:Remote=false
B:ServerVote=false
B:SignTools=true
B:Teleport=true
B:Tickets=false
B:WEIntegrationTools=true
B:WorldBorder=false
B:factions=false
B:mapper=false
B:perftools=false
}

And it is still happening?

Can you post your latest.log showing the chat messages?

Please post both the log without Forge Essentials and the log with FE.

Lastly, please provide me a list of the mods that you are using so I can try to replicate this issue.

Chat is disabled for a long time, he does not write anything to the logs.

I will write a list of mods later
