Select the eraser tool and then look at the [context bar](https://aseprite.org/docs/context-bar), which is above the canvas and below the sprite name tab and the [menu bar](https://aseprite.org/docs/menu-bar). What do you see? If the eraser’s opacity is 0, then change it to 255.
If you see the mouse cursor is a red circle with a diagonal strike through, then look at the [timeline](https://aseprite.org/docs/timeline), which shows your [layers](https://aseprite.org/docs/layers). If the padlock to the left of the layer’s name in the timeline is ‘closed’, then the layer can’t be edited until it is ‘unlocked.’
If none of that works, what [color mode](https://aseprite.org/docs/color-mode) is your sprite? Go to the menu bar, `Sprite > Color Mode`.
