I really like the Blue Captcha demo but when activating the plugin, I get 1 error message on my site backend and plenty of them on my site frontend. They all concern other plugins. Do you know what's going wrong ?
Deprecated: Assigning the return value of new by reference is deprecated in /homez.9/ajwan/www/wordpress/wp-content/plugins/dp-widgets-plus/dp-widget-plus.php on line 431
Same error + many other errors concerning the plugins : Dynamic to Top, Search Everything and Dynamic Widgets
