Recently we upgraded our commenting solution to the newest version offered by Disqus (our vendor). We were one of a handful of McClatchy markets who made the transition as a test.
What we discovered is that all of the issues had not yet been worked out, and it isn't ready for prime time. So we've rolled back to the previous version.
We know that some users have had trouble logging in to make a comment. We are not sure whether rolling back to the previous version will solve this issue, but the support team at McClatchy is aware of the issue and has been looking into it.
