I am trying to zip a complete folder on our server using your class as I have very good experience with it in the past. Now I am running into a Servererror (500) when I am trying to zip a folder that contains ~1000 images. I am not sure if it a problem with the file type (images) or with the amount of files. Other folder work perfect with the script, so I assume that the script works. Do you have any advice where the problem can be as I cant get any more info from the server (just crashes with 500).
