hello there

I recently started a sky blocks server I added a plug-in to let people to do /shop called economy shop GUI. I added luck perms to allow people to do /shop and added it to the default but if people leave the server then join again it says you do not have to permission and I have to reload the server for them to have with the permission /Re-confirm can you help?

Any errors?
Any messages when they join?
What is your server setup? Is it a network?
