Does not appear to work in 2.6.1.
This plugin does not seem to work in 2.6.1 (it didn't work in 2.6, either). Users with the moderation permission do not see anything regarding warnings anywhere (nor do we see anything regarding the related plugin for temp bans). Unless I'm missing something (please let me know if I am!), I think this plugin needs to be updated. If anyone would like to point me in the direction of a similar alternative, I will also be grateful.
Thank you so much!
