File data for export is empty! error message appears when I try to upload a large CSV file for import with the import tool. This is only affecting one of my files, not all of them. This particular file is very large, about 113 MB, but I have been able to import it before. Not sure what has changed, but this is also not a very helpful error message.

please check these directives on the your phpinfo() page (see admin->system->settings->system button phpinfo()

upload_max_filesize
post_max_size
)
