"It's Not My Job"

What the fucking hell happened to Blogger/Blogspot/Bugger? Had an entire effing post done, it kept telling me "Invalid Input" but wouldn't say why, & the labels weren't showing in preview. (The "Reload this preview" button doesn't work anymore either.) Then I hit Publish & it went to draft, when I hit Publish & it appeared live w/ only the title. See?

No labels now either.

Secs. later: Labels show live, but didn't in preview.
