WordPress version: 3.4.2
WordPress SEO version: 220.127.116.11
I recently upgraded to WordPress SEO v 18.104.22.168. I have users who are contributors reporting they are unable to change their password or edit any of their profile details. When the user clicks the "update profile" button they receive the message "Are you sure you want to do this?", but are unable to proceed further (i.e. no yes/no option, etc). Admin users do not experience the same issue.
I narrowed the issue down to the WordPress SEO plugin by disabling all plugins, reactivating them individually (deactivating after confirmation and repeating) until I found that the WordPress SEO plugin is causing this. I also have another WordPress instance for another site. I did not have the SEO plugin installed on this site. I installed it, added a contributor and expereicned the same issue. When the SEO plugin is disabled on both sites, the update functionality works as designed. I did not experience this issues until the 22.214.171.124 upgrade.
