Had you just played a game that got you up over the 4800IP mark? Try closing the client and logging back in, and see if it then registers that you have enough IP. It'll be useful information for trying to work out the cause.
Log in to the old client. I believe on the log in screen there's an option on the bottom right to log into the Legacy Client. I had this issue and that fixed it for me.
So uhm, after playing 2 - 3 more games. I checked to see if I can buy the champion again. And this is what comes up. http://image.prntscr.com/image/11315c48399643b4b9e4bab9aa3e123a.png It is asking me to spend 5118 IP to get a 4800 listed champion. Most likely a bug and I hope a Riot staff see's this so they can relay this to the team.
