stain around fuel cap

Hi guys, recently I found gas spilling out of my fuel cap after negotiating a corner.

what could be the problem? The O-ring/gasket is gone? I'm using a yz4 oem fuel tank with my stock wr4 fuel tank cap.

But it only start spilling gas recently, and it causes my sticker to peel and ugly stain around my tank cap. Anyone have any idea how to remove those stain. HELP!
