Hello,
I search the forum but I couldn't find the answer.
We use the Pro version and for every file we add our own Thumbnails.
When I change some files (update, move etc...) some thumbs of other
files disappear. I need to remove the existing thumbs and need to add the thumbnail again. It's not easy to reproduce because it happens "on the fly". Spontaneously... and it is a live business website.
It's a bit hard to describe/explain but I hope you understand.
If you need more information, please ask.
Best regards,
Vincent Volmer
