articles / single article not working in 3.8

Yes, please Private Message credentials along with a specific article that fails when you enable both comments and social sharing buttons. It's strange that they both are required for the error to occur, but the article will work with either one enabled (but not both). Either way, we'll gladly investigate and get you going. We have a release scheduled to come out over the next few days. If there's something we can get into that release to prevent this problem in the future, we absolutely will.

Thanks,
Alex
