I'm having a weird issue with my forms styles after my upgrade to WordPress 3.2.1 from 3.1.4 (though I can't say for sure that this hadn't been happening sooner than the upgrade, it's just my best guess).
The form stylesheet loaded fine previously, but now it seems to be missing. In fact, if you look at this page you can see that none of the Gravity Forms' CSS or JS is loading at all: http://usarivercruises.com/leave-us-a-testimonial/
These forms were functioning perfectly for a long while, so I don't know what has changed. I certainly haven't made any changes to these forms.
They are all called via shortcode on their respective pages, "Output CSS" is checked in the settings, and my theme has both
wp_footer in it (I'm running this on the Hybrid framework).
I should add that the CSS loads correctly when I preview a form.
And that I've switched to the TwentyTen and TwentyEleven Themes and the CSS doesn't load in either of those as well.
