Since Drupal 7.91 update only images displayed directly through the Drupal interface (e.g. "thumbnail" displayed in the Drupal node edit form) work. Requests to any other image style (s/d/files/styles/new_style/public/filename) return file not found.
I tried adding
$conf['image_allow_insecure_derivatives'] = TRUE; to the settings.php file. I tried adding
$conf['sa_core_2022_012_override'] = TRUE; to the settings.php file.
I've tried adding the imageinfo_cache module, but it didn't help.
