New editing restrictions?

OK - here's more info. It turns out I could edit and save both of those sample posts, but I had to go into the advanced mode to do so.

At least now I know there's a work-around to whatever the issue is.

Good catch. Saved me from the embarrassment of looking at my mistakes for ever.

More insight, based on additional experimenting with other posts where I also have the editing restriction. The common denominator may be inline images. It seems presence of any inline images requires post edits to be saved in advanced mode.

EDIT: Having those inline thumbnails now expanded to full size images is going to take some getting used to.
