Could be that there is still an active selection somewhere, even a single pixel that you do not notice. Make sure selection is off. Select -> None
Another possibility is trying to paint outside the active layer. The yellow dotted line is a layer boundary. Shows when the layer is active.
There is a pixel lock for each layer, toggles on / off Paint tool will have a 'barred' icon next to it and a message in the notification area (bottom of the window)
Trying to paint on a non-visible layer? The brush will have a 'barred' icon next to it and a message in the notification area
None of those? Please post a screenshot of the whole gimp window showing layers and tools options.
