I can’t put an attachment here. but when I click on “chart library”, the page that appears is this one https://observatoire.franceboisforet.com/observatoire.franceboisforet.com/wp-admin/admin.php?page=visualizer
the last change that I do it’s upgrade my Plesk version but with the old version, I had the same bug with the plugin.
Yesterday I find a way to access to the plugin, I have to go to the list of all my extensions, find vizualiser and then, click on “library”. that’s weird that the plugin doesn’t works if I go through the dashboard
