I can't help you with this as I am on mobile data and I don't want to waste my data. Could you perhaps describe the problem you are having...? Also why did you tag this thread with a suggestion tag?
It might be a bug that's in another plugin maybe? What plugins do you have? Is the issue reproducible without any plugins except PurePerms? What version of PurePerms are you using?
Not weird, you need the latest builds from https://poggit.pmmp.io/ci/poggit-orphanage/PurePerms/PurePerms and https://poggit.pmmp.io/ci/poggit-orphanage/PureChat/PureChat. Alpha8 is not yet tagged so there are no releases on Poggit for that API version. Soon!
