I am able to import .csv lists using the upload method up to a certain size. But at some point, it fails to upload it gives me a 'file not found' error by the FTP form. I took a list with 25K users on it and got this error. By gradually paring it down, I found that I can upload files of 15K users or so.
I don't think this is about illegal characters, because I removed all single quotes and commas.
Is this about the max file upload setting in php.ini? Or is it just timing out?
I am on version 1.87d.
Thanks,
Rich
