Corners showing!

Hi folks,

I have been trying to get rid of the corners for the various text boxes on my forum (either romove or make black so can't be seen). I have tried everything but the left hand ones (only) are still showing up and unfortunately they are white so very visable.

Can any one help me with this, please?

Solved it myself, some of the changes made yesterday wouldn't work.. re-did them today and they work now..go figure! lol
