File type upload poblem

Hi,

I have been having a lot of problems with Advanced file upload when uploading ZIP or RAR files created on Windows machines. Even though I can upload these files manually via WP Admin > Media > Add new, same files can not be uploaded via Advanced file upload of Caldera forms.

I am constantly receiving “This file type is not allowed. Please try another.” error.

If a zip file is selected from a Mac machine the mime is application/zip, but when on Windows machine it is application/x-zip-compressed.

When defining allowed file types on Caldera Form setup, the “zip” extension only includes application/zip to the data-config attribute of the input. See below.

{“custom_class”:””,
“multi_upload”:1,
“media_lib”:1,
“multi_upload_text”:”ADD FILE”,
“allowed”:[“application\/zip”,
“image\/jpeg”,
“application\/pdf”,
“image\/png”],
“max_size”:134217728,
“notices”:{“file_exceeds_size_limit”:”File exceeds the maximum upload size for this site.”,”zero_byte_file”:”This file is empty. Please try another.”,”invalid_filetype”:”This file type is not allowed. Please try another.”}}

I believe this might be the problem, and just because of this it caused a lot of issues and I hated the plugin.
