Abstract. In this paper we discuss some convergence and divergence properties of subsequences of partial sums and logarithmic means of Walsh--Fourier series of functions in the uniform, and in the $L$ Lebesgue norm. We give necessary and sufficient conditions for the convergence regarding the modulus of continuity of the function. It is also proved that there exists a bounded function for which the logarithmic means converge and the partial sums diverge.
