i did accept the summoners code many time, at least i pressed the buton, and last time i'd read everithing, but im still greyed, whats happening here?

Yeah me too, Wont let me pass that screen. Anyone know why?

If you are just clicking on the shield under someones name, that does not send you to the acceptance page

Go to http://www.leagueoflegends.com/account or "MY Account" at the top of the page. the correct link is under "Reputation." A flash window should show up with the code and the option to accept or decline.

If you tried that and are still having problems, maybe check if adobe flash needs an update?

I understand it helps if you log out, and when you log in, go DIRECTLY to the acceptance page and Accept the code. If you post or play in the forums first, it doesn't work.

Try using a different browser. I usually use google chrome, but had to fire up internet explorer again to get it to work.
