When user tries to upload a file, the following error is received: "Server error: Upload directory is not writable"Asked by NNC2015 on January 01, 2015 at 11:16 PM
We sincerely apologize for that - this was caused by a full hard disk on our end - your form should work normally now.
I did a test on your form - looks good.
Kindly check and let us know.
