I’m still unsuccessfull with Wallabag V1, but I’ve resolved my problem with wallabag V2 with the solution in this post :
J’ai mis à jour sur Github, mais la solution pour le bookmarklet est d’éditer /etc/nginx/domain.tld.d/wallabag2.conf
et dans location @wallbag2 remplacer:
rewrite ^ /wallabag/app.php$is_args$args;
par:
rewrite ^ /wallabag/app.php?is_args$args;
and everything work fine in Wallabag V2 now, so I don’t care about Wallabag V1
