Same problem, also posts with green lights have changed to amber/yellow. Changing WP Permalinks settings made no difference. Example: Page analysis tab shows:
There are 1 words contained in the body copy. This is far too low and should be increased (post contains 665 words)
The keyword density is 0%, which is a bit low, the keyword was found 0 times (presumably because it can’t see any of the text)
The page title contains keyword / phrase, but it does not appear at the beginning; try and move it to the beginning (it’s in the first sentence)
Have not installed any new plug ins – this started happening randomly since the last update 1.2.5
Hmmm?
