 * Just purchased the pro version. Cannot activate it due to fatal error: Fatal 
   error:
    `Cannot redeclare YUZO\_strposa() (previously declared in /var/www/web9/
   htdocs/wp-content/plugins/yuzo-related-post/autoload.php:6) in /var/www/web9/
   htdocs/wp-content/plugins/yuzo/autoload.php on line 6`
 * Do I need to remove the free version before installing pro?
 * Edit: Resolved: needed to deactivate the free version
