Did you mean that E and B are of the form exp(kx-wt)?

No. I may have a mistake somewhere. That is possible. But there is nothing wrong with having zero divergence. In fact unless there is a net charge concentrated somewhere one would expect the divergence of E to be zero. And if the divergence of B is not zero then there would be a problem.
