Missing Motd button image

I recently installed a motd addon for my DarkRP server.
it all looks smooth and nice, except for the button’s icon(.png). there is just the normal error scheme (purple/black)
I did check that all the files matches the code’s path.

So… Do you guys have a clue about what did go wrong?.
