[Plugin: CSV Importer] got error Failed to load file, aborting.

yahoolivestream: Most likely, your server is not properly configured. I’d suggest looking at Apache’s error log.

i had the same problem recently and found out it was because the file was just over the size limit (which for me on my server is 2.0M). try splitting your file into a couple of smaller files or increasing the limit on your server in the php.ini file (i hear that helps but i just split mine into two and it worked).
