MailPoet

Hi Mailpoet,
thanks for this plugin.
I have a problem:
Notice: get_currentuserinfo használata nem támogatott a 4.5 verzió óta! Ezt javasoljuk helyette: wp_get_current_user(). in /chroot/home/alehetos/cipokeszito.eu/html/wp-includes/functions.php on line 3658
In this functions.php file not exist this: get_currentuserinfo, and can not change this to: wp_get_current_user()
I dont know the php version on my server.
How can be solved the problem?
Regards: Ernő
