Hello,
Sorry, i don't succeed in the following.

In https://peres-family.eu/_Photos_de_voyage/Ethiopie_2015/
my 11 folders are at the top, at right of the "house".
Fine.

But in https://peres-family.eu/_Photos_de_voyage/Ethiopie_2019/
the folders are not shown.
Rather, they are shown when the mouse goes over the "menu with 3 bars" at the top.

I really don't see the difference between the parameters of the two projects.

Really not urgent, but help or comment be welcome ...

Ha ha i would never have guessed.

Because it becomes clever.
And because there is a problem of traduction (i am using a french version).
"Use button above" should be translated with
"Utiliser le bouton au dessus de"
and not
"Utiliser le bouton ci-dessus"

Many thanks : fast and precise answer, it becomes a pleasure to have problems ...
