Message Editor Buttons Missing?

[Frankenfurter]

I'm not sure if it is called the Message Editor; however, I modified its colours and it was completely fine. However, I came back today and the buttons cannot be seen (as can be seen in the attachment). I'm not sure what I've done.

Thanks!

Check the xenforo/editor/icons.png sprite exists in the style directory.

Thanks so much :-D seems that I've accidentally moved it!
