Hello, is there a command or a technique to make a wipe of the ranks?
Without delete the other groups not used in the ranking?
Thx

If you are trying to reset everyone's hours back to zero, then you will have to delete the data of either ConnectionDB or PlaytimeTracker, which ever you are using, then PlayerRankings should automatically demote them all to the lowest rankings possible. But if you wish to remove one of the current ranks that you have, then simply delete the rank in PR's config and remove it through commands or datafile from BetterChat.

Thank you, I ended up succeeding earlier. I proceeded to the suppression of the fifty groups that I had to be sure that the players would not be in different groups. And I delete both connectionDB and Playtime tracker. I have a little panic for wipe today or we changed a lot of chess and wanted to put everything back flat. Thank you for your responsiveness.

If you wish to restore everything, then simply go in your backup files and grab the necessary files to restore.
