  • I’m not sure if it helps (6 months later), but problem lies in the Nextgen Gallery cache. There is a button to clear cache in nextgen options or the other way would be to use url – https://www.example.com/something?ngg_force_update=1 (replace with your site domain etc.)

    I will try to implament this url into refresh what happens after the images have been uploaded.
