Hi hazlebury,
I can assure you that the importer still works.
The 0 / 0 message implies that there is a server issue on your end, or possibly an improperly formatted CSV file.
The first thing you should do is try the upload with the example CSV file. This will help you determine if the issue is your site/host, or your CSV file. Then please read the “I have a problem with the CSV importer” section of the documentation.
As a last resort, you can also take a look at this previous support thread: https://projectdmc.org/support/topic/error-the-uploaded-file-is-not-a-csv/#post-16356180
The issue was that the demo file has spaces in the filename. Once I removed the spaces, it worked.
Excellent, and thank you for responding with your solution!
For ease of access to anyone else who may see this — this is a host dependent issue. From the “I have a problem with the CSV importer” section of the documentation:
Make sure that the filename is unique. Sometimes hosts struggle when you upload a raw file with an existing filename. So try renaming your CSV file something A) unique, and B) something that has no spaces or special characters.
