Spigot 1.12.2 latest
LuckPerms 4.2.36

I just noticed that verbose mode details are not displayed in the console/log. All I see is
VB > playerName

The details were displayed until recently, certainly end of May). I don't see a relevant configuration change since 4.2.2. Did I miss something?

Are you using a locale file?

Yes, I am. But I edited only the prefix.

# diff plugins/LuckPerms/lang.yml plugins/LuckPerms/releases/4.2.36/locale/en_US.yml
5c5
< prefix: "[LP] "
---
> prefix: "&7&l[&b&lL&3&lP&7&l] "

plugins/LuckPerms/releases/4.2.36/locale/en_US.yml is a copy of the current https://github.com/LuckPerms/locale/blob/master/en_US.yml.

Delete all of the other entries from the file

Well, that worked. But hardly the expected result. As an test, I tried

# LuckPerms Language File
# Locale: en_US (English)
# Author: Luck

prefix: "[LP] "
verbose-log: "VB > {0}"

(copied from the locale file, and again removing only the formatting codes). It displayed only
VB > playerName

In order to get the equivalent of the default verbose-log display (minus some of the formatting), I had to supply

verbose-log: "VB > {0} - {1} -{2} {3}"

Yes, the locale file is out-of-date at the moment.

The correct replacement is here:

Thanks.

I was leaving this open until the localization files were updated. Do you want me to open a separate ticket?

The locale files are generally updated once builds are pushed to Spigot/Ore as "stable". These changes aren't backwards compatible.

Thanks.
