When i'm uploading multiple Images in backend everything looks fine first.
- All Images are uploading
- All Images are shown as Thumbnails
but after saving, about 50% of the images are gone. For Example: I upload 10 images, every image is shown in the form, but after saving i have just 5 or 6 images assigned.
I don't get any errors, not in Developer Console, not in PW logs, no PHP Errors
If i drag and drop them one after on the upload area (same files) and wait until thumbnail is shown and then save the form, everything works fine.
If i try the same form local on a XAMPP installation, everything works fine.
Any idea ?
