I'm having to re-enter all of my keywords, titles and descriptions for the All in One SEO plugin after using the WordPress "quick edit" function to make some changes to categories and tags. As far as I recall, this is a new "feature" of the plugin and really is a bother that it isn't working the way it used to.
I don't know if the problem is related to the All in One SEO pack plugin or the latest version of WordPress but I'm thinking that it is the plugin and not the platform software which is the problem. Either way, this should not be happening. Having to re-enter critical SEO information for posts and pages that have disappeared generally renders the "quick edit" feature of WordPress useless.
