I have an issue with the Field X with File Upload as the field to duplicate.
The first issue is that I cannot get docx files to upload. I have tried going to the media manager configuration page and adding docx,DOCX to the list of Legal Extensions (File Types). In fact I have tried various combinations of putting it in the different places on this page and also tried adding the application/vnd.openxmlformats-officedocument.wordprocessingml.document to the legal MIMEs
Despite all of this I continue to get Illegal Extension
The second issue is that I cannot get the uploaded files to display in the content apart from the first file. If I upload multiple files I get a link to the first file and then the rest only show as an empty <li> tag.
My File Upload is set to no storage and the Field X is set to Custom / Article / file_upload
It seems like it is working as all the files appear int he correct folder in the Media Manager, but only the first one displays, despite their being the correct number of <li> tags for all of the files.
Thank you in advance for any help you can give me.
