I'm trying to import a collection of ~10000 cards using the CSV import. I've tried several times, but all I get back is "Error: The server encountered a problem trying to import your file. Please check that it is a plaintext csv file and try again.". I'm sure the file is a plaintext csv file, it uses the same format (headers) as the one I get from the export, and the same line endings (\n).
What else could be wrong? Could you fix the upload so it gives a slightly more detailed error message?
