Uploads/tmp folder is owned by apache and has correct rights.
If I upload images they appear in uploads/temp folder as expected.
When I upload three images at once and I do not publish the ad and start removing the images I just uploaded only 1 out of three is removed from temp folder. -> Not good.
Now if I upload only 1 image, do not publish ad and remove image again the image is indeed removed from the temp folder. -> Good
Scenario Publish Ad:
Upload images -> I do publish ad -> OK - all images have been moved from temp folder to image folder and ad is published -> Good
Scenario Edit Published:
Edit published ad, removing images OK - images are removed from image folder -> Good
Now, I am pretty sure if 1 gets deleted or all get moved there is no issue of folder rights/ownership.
The issue is ONLY happening when uploading more than 1 image and in all cases only 1 image really gets deleted and all others are not removed from temp folder.
Couldn't see any issue here, when I click on Delete on the frontside, the file in /oc-content/uploads/temp is immediately deleted...
