Thank you very much to Dennis Santana for bringing this to my attention. I’m adding a new feature (I hope) to KJD-IMC to help me with my weekly reading and round-up and I screwed up my permalinks. Once he clued me in that the primaries were broken, I fixed that and it solved the problem entirely.
I should know better, I really should. ITIL-certified and I give developers grief when they don’t follow good change management processes.
