Hello
thanks for your fast reply, sure!
So I have like 120 pdfs on my site uploaded as single packages. Some weeks ago there was automatically a pdf thumbnail of the first page generated, which was usable with the [thumb_url_1200x600] Shortcode in linktempalte “image_hover”.
Now there are no thumbnails showing, whether in the package backend nor in the frontend.
I can still use icons, or manually add a featured image to the package which works great.
