After update my site with latest Yoast SEO 3.0.3 Strange problems: In Windows 7 with latest Google Chrome explorer the editor TinyMCE Advanced is working, but SEO Tools page is blank.
In PC with Windows 10 with latest Google Chrome explorer the editor TinyMCE Advanced disappear… and SEO Tools page is blank too.
Same PC with windows 10 in Firefox the editor TinyMCE Advanced is working!!! (SEO Tools page still blank)
