WP SEO: 188.8.131.52
Installed and works on a previous version of WP, so I have observed how it should work.
When I type in a Focus Keyword, the meter spins "forever." When I go to Page Analysis, it says Focus Keyword not set.
I've concluded from reading many, many, posts that there is some compatibility issues with WP 3.5.
When resolved, I hope someone will let me know the solution or a work-around!
