Could you lend a hand and help me to solve this? Not sure what exactly happend as I didn't really change anything as far as I remember.

Best regards and thnaks in advance,

How exactly are they not able to download? Download dialog blank? Zip file empty?

I logged in as a customer and tried it myself.

When I click on the button to download all photos in a zip file the site just keeps loading (see the screenshot).

Downloading them one by one is no problem.

Hi Tim,

I was just busy with the current issue and found another issue that relates as well to files and file handling. When I drop a folder with JPGs into sy-upload and then try to "Upload Photos" the same issue appears. The website tries to start the upload but gets stuck on that process. I don't know if it is related to that but I thought I better mention it. 

As we are running the website on Windows Server instead of Linux/Unix which we were using before it might be that some PHP extensions are not enabled or installed that are needed for Sytist to function correctly.

Would it help if I provide the php.ini?

Best regards, Andre

Same issue here with ZIP files hanging. Any known issue? I will send an email.

No known issues. Will be server related. 

Like above, You can email me the following for me to look into it: 

Hi Tim,

All good, my website guy ran some PHP updates and that got it running properly again.
