So sorry that you aren't 100% happy with my module...
As you wrote I have tried to help you but as you could not provide the logs for your server it is impossible for me to try and solve your issue with why the Warning is posted.
If you reduce the logging level for Joomla from Maximum the Warning will not be visible and SFU will still work fine...
Please let me know if you can get hold of the logs.
Regards,
Anders
