glgdev on "[Plugin: WordPress SEO by Yoast] Wordpress SEO section in posts and pages not functional"

Hi, same here, nothing happen when I click on the drop down arrow... any fix on this ? For me it happens when I added multi site after the main site was made (and yoast was working nicely at that time)... now since multi site is activated, not pssible to edit a single thing.
Any advice very welcome ;-)
