I'm working with a "Pro" version of this plugin that was purchased directly from your website not even a month ago.
I'm not sure how the paid "Pro" plugin is different from what you're offering here for free and would also like to see that clarified on the plugin description page on wordpress.org, as well as on your site.
When this plugin is activated, if it's checked to "boost" a specific page, and then unchecked later, the all the plugin content boxes do not disappear after being removed from a page.
Basically, it makes every edit page 2 to 3 times longer -- even when the plugins features are not in use on that page. It's an issue, especially when there are already other critical plugins bulking up edit pages.
How do I make it disappear when not in use (when settings are off for a specific page) ?
Also, it seems to have a conflict with woocommerce. When activated, the product names disappear -- meaning I cannot edit the products. It happens only when SEO Booster is activated.
For now I've just turned SEO Booster off. Please keep us posted.
