Disk space becomes full without uploading large docs, images, etc

domain is
tecstub.uknowva.com

We have checked and found that since yours is a free account, it has limited space which was exceeded as uKnowva keeps writing system logs, etc, hence you were unable to export any file from the system. I have temporarily fixed this problem, but this will surely come again in future again. We request you to please upgrade to a paid subscription to get more disk space. Moreover you get personalized support as well. Please connect with our sales team for more details on this.
