I have just had to re-do the configuration of the website to allow comments to be posted. I guess there is a problem with the way that I had things being addressed and I needed to change it to the old way and then re-build the entire site in order for it to work again. If you’ve wanted to post a comment recently but got an error like “No valid data was submitted” or something, please feel free to try again. Everything should be working fine now.
