I am using Qumana editor for posting to my blog. There are occasion when I have received few errors during publishing, The most common publishing error I have received is Read Timed out. This normally happened
to me whenever my tags are not properly closed or even if certain ping services are not available for publishing.
The other error server failed to respond is received when the Internet connection is down while posting to the blog or the blog site down temporarily during the time of posting.
