Over the past two days, I have written and modified the same post for 5 different channels 4 different times. They will neither save as draft, nor go through and load in the scheduler, nor will they post when I try to push it live now. In every case, the little "Publishing Progress" screen pops up and just spins with "Post is in progress," but never progresses past that. I have no idea what's going on here and it is wasting my time and my effort. Recommendations please.
