To add a bit more weirdness to the diagnostic symptoms:
I can see the prefooter pictures and links when I go from “preview changes” button. If I navigate to another page and come back I will still see the prefooter as it should be. But now, the text from the three posts that make up the plx page does not show. The photos from those posts show fine. If I edit the posts, the text will show in the “text” editor window, but is blank in the “visual” editor window…before posting this and making a fool of myself I find that the text is still, in fact, there but it’s color has changed to match the background (which is a black to gray gradient) No, I didn’t change the color of the text. I’m at a loss. Thanks so much for your help.
