During my absence, we were notified that many readers were experiencing difficulty while viewing certain pages and leaving comments on others. After some research, we determined that the two issues were inter-related, tracing both back to a recent Blogger update that was producing similar symptoms on many other blogs. This upgrade added Blogger support of threaded commenting, which allows a reader the option of leaving a general comment about the article, or responding to another comment on the thread.
Unfortunately, the upgrade contained a few bugs, so pages containing previous comments appeared as a completely blank white page. Pages without comments could be viewed, but readers were prevented from adding comments. As a temporary fix, we changed our comment settings about six weeks ago from embedded (threaded) to a pop-up window.
We have now been notified that the issue has been fixed, so we’ve re-enabled the threaded comments feature for all pages. We’ve spot-tested several pages using the latest versions of IE, Firefox, and Chrome and encountered no problems. Still, if anyone has any future problems with commenting (or any other technical issues), please don’t hesitate to let us know. Thanks again for your support and feedback.
