[Client/Store] Gameplay Tab not loading

Gameplay tab in the store is not working. Comes up blank. I looked at it earlier, saw that the XP boosts are 50% off on my newly created account, so i load some RP, buy a champ, and as soon as i go back to gameplay section, it goes blank and does not load. It's the only section that is not loading. Tried relogging, but to no avail.
