Hello,

Good to know but which one?

$ grep -i warning  log_2026-06-20_bc893fd64e42e82494ef18b5d22a2987e7269e41.txt
$
I screened the log but didn't catch the file
I generated again all the thumbnails, no error

I suggest a new button to be added in this case. When the user click on it, the details filename(s) are displayed?
Thanks
Phil
