Trouble posting when logged in

Hi all,

I'd hoped to paste a copy of my explanation of my problem right here, but it's not accessible, so please allow me to post this as a simple test of whether or not the forum will accept this new thread.

Some 13-14 hours ago, the forum would give me strange messages when I clicked Preview or Submit Post.

I don't know what will happen as I click them now!

OH! Preview worked! ...that's a good sign!

(I have screenshots of the previous nightmare.)
