after activating the plugin all my blog pages are showing this:
Notifixious Settings Please enter your Notifixious login information. If you have forgotten your password, please request a new one here. Don't forget to install our widget as well to allow your readers to choose the channels on which they want to be notified! Fatal error: Call to undefined function wp_create_nonce() in /var/www/web6/web/wordpress/wp-includes/functions.php on line 1383
I had to manually delete the plugin.
