After updating to the latest version, one of my staff members was unable to login and was sending this error to console. http://prntscr.com/nu78hk and recieving this error when logging in http://prntscr.com/nu8603

Shortly after trying to reupdate all plugins, it began happening to me aswell.

We need more information like what server version you run, if it is in online or offline mode and if it is part of a bungeecord network.

Also delete the libs folder in the LuckPerms folder and let LP download the jars again (restart the server for that)

This is a bungeecord network, the version is 1.8.8 . I also deleted the lib folder in the bungee lp folder + the hub servers lp folder and restarted both and am still receiving the same error on login after updating from 4.4.22->4.4.25

What happens in the bungee screen on login: http://prntscr.com/nuhhlp

*The only way to succuessfully use LP is to revert back to 4.4.22 as no one runs into this error unless I upgrade to 4.4.25

The screenshot doesn't show the actual error itself (the stacktrace)

Weird, there were no changes between those versions that could cause that error. That error while setting a group should happen on 4.4.22 too.
Looks like you messed up the database config options or changed the db password. Check the startup log for details
