I keep getting the error when trying to upload certain accepted file in EE. I have been struggling to get some files uploaded to EE but cannot due to the following errors.
The extension of one or more files in the archive is not in the list of allowed extensions: xl/worksheets/_rels/sheet1
Not sure why this is happening. The file comes from Google Sheets and is part of their download or export feature. I download it locally as an xlsx file then attempt to upload it to EE. It does not work. What am I doing wrong?
Would it be possible to attach the file(s) in their current form that you are trying to upload so that I can try? I've never experienced the problem and have uploaded several files. Remove any personally identifiable information, then upload attach them here or to me in a PM to me if you prefer. If that doesn't work, zip them up and upload as a zip so we can extract them and try uploading ourselves.
Hope that's helpful.
