I installed this theme on a local site without any special problem.
However i state that on the top left section the date (in french language) is labelled as this: mercredi, octobre 10, 2018
How can i do to change to: mercredi, 10 octobre 2018 ?
Hello chti56, Right now we do not have that feature, but you can send feature request from https://themeegg.com/request-new-features/, so that we will update the feature in upcoming version of the theme.
