Forum Skin Problem

[qcharu]

I was clicking on skins a few days ago and when I hit the mobile version it stuck. Now I can't go back to default. I get this message:

Your submission could not be processed because a security token was missing.

If this occurred unexpectedly, please inform the administrator and describe the action you performed before you received this error.

Any ideas?

Scrolled all the way down and in the bottom left hand corner there is a tab that says normal version. Clicked that and page went blank. When I came back to the forum it was back to normal.
