i want to ask that why i can not buy any items from all of the main shop for about 3 days?:/ is there any way the solve this problem? thanks:)

Do you have 100+ items in your inventory? :)

Switch to Firefox. :)

It's a glitch with internet explorer, the button is greyed out already right? Like Scarsdale said, you can solve it quickly by switching to firefox if you can. If not, then sit tight I guess D: I'm sure they'll come up with a fix soon but firefox works better with subeta generally.

hm... thanks,i 'll try for it
