# Generalized linear mixed effects models - Poisson family with log link

When fitting a GLMM with family=poisson(link="log") in lme4, I understand that the coefficients for the estimates of fixed effects in the summary() output must be exponentiated to be back on the scale of the original data.

1. are the standard errors for fixed effects in the summary() output also logged and need exponentiatiating? I have seen conflicting answers on other questions, some saying the standard errors are on the original data scale and others saying they have also been logged like the estimates
2. do the random effect standard deviations/variances need exponentiating or are they unaffected by the log link so are still on the original data scale anyway?
