We've got all the max settings set up OK as per https://craftcms.com/support/upload-troubleshooting, but we are still getting errors. The log file just shows this, nothing more:
2014/10/24 11:26:35 [error] [application] Uploaded file was empty
What else should we be looking for?
craft/storage/runtime/logs/phperrors.log
file and if anything related is getting logged there.
