Hello! I have a similar issue with “Drag&Drop uploader” [mfile]. Files are uploaded to temporary folder but not attached to the E-mail. Also files are not deleted from temporary folder, but that’s probably ok as they are never attached anywhere.
Single uploader [file] and also multi uploader [multilinefile] both work great. That means e-mail setting should be good and also be able to send Zip files. I also checked that ZipArchive() extension is enabled on hosting. File Attachment tags should be correct.
It would be great to get this working as I just like the look and feel of that uploader ??
