On Lebesgue continuity on classes of $\bar{\psi}$-differentiable functions.
In this paper estimates group of deviations of Fourier sums on the spaces $C^{\bar{\psi}}$ expressed in terms of the best approximation of $\bar{\psi}$-derivatives of functions in the sense of A.I.Stepanets are found. The sequence $\bar{\psi}=(\psi_1,\psi_2)$ are quasi-convex
