Do you have any chests available right now? Like, on your profile banner, are all the chests grayed out?
Not those chests. He was asking if all the chests are grayed out on the front page of your profile, not in the champions tab. If the chests he was asking about are all grayed out, then you cannot earn anymore chests until you get another slot open. You get one extra slot per week.
Ahh, yes they are... I am feeling like an idiot right now... Thanks for replies :D
