Even though PHP ZipArchive is installed fine on my server, the zip download fails. True, the ZIP file is created and downloaded to the Downloads folder. However, this file is extremely small (sure without pictures) and cannot be opened. Instead, the message "ZIP file is invalid" appears.
The folder contains 75 JPG images with filenames like "2021-05-08_005.jpg"
What could be causing this problem?
Thanks for support and best regards from Basel
