Issue with Mac-generated .zip files

[jonathanold]

I am trying around some things related to the import of .zip files. For that, I unzip the files on my local (Mac) machine, change text in the .txt file, and then make a new .zip-file. However, when uploading this, I always get the error message "File not uploaded properly. Try Again!".

Can you try to make the zip file using zip command?
