site blank after activation

I am also having the same problem

And this is the error log

PHP Warning: Missing argument 3 for _doing_it_wrong(), called in /home//public_html//wordpress/wp-content/plugins/wp-cdn-rewrite/wp-cdn-rewrite.php on line 49 and defined in /home//public_html//wordpress/wp-includes/functions.php on line 3040

PHP Fatal error: Class ‘Voce_Settings_API’ not found in /home//public_html//wordpress/wp-content/plugins/wp-cdn-rewrite/wp-cdn-rewrite.php on line 92

here is the solution

go to the plugins folder

open wp-cdn-rewrite.php

and add

if( ! class_exists( ‘Voce_Settings_API’ ) ) {
require_once( $path_to_voce_settings_api . ‘/voce-settings-api.php’ );
}

Now try activating the plugin it will work.

This should now be fixed with the latest version of the plugin.

Thanks!
