Approving entry remove al images from gallery
It happens when entry is created by user without rights to approve own entries. Here is step-by-step instruction to recreate problem
- add entry with images uploaded to the gallery as user without permission to add autopublish entries (I use for it visitor)
- entry is saved and when you access edit entry view in the back-end images are there
- publish entry from the entry list or from the entry edit page
- when you check entry again images are removed from the field
