@LPetelik said in Images are not deleting:

When deleting an image in FOG Management, we get the authentication window and the user authenticates then clicks delete. A second window appears and she’s not able to click delete because it disappears too quickly or she is able to click delete but the file still remains. I then go in using ssh and delete the file for the image.

Kindly ask her to disable all extensions in browser and then give a try.
Most probably any extension is creating this kind of issue.
