[PHP] Problem z wordpressem Opcje

[asdkrzys]

Witam,

jestem zielony jeśli chodzi o jakiekolwiek programowanie, potrafię tylko postawić wordpressa i w nim wykonywać proste modyfikacje.
Moj problem polega na tym, że w świeżo zaintalowanej templatce do WP wyskakuje błąd.

Kod

Fatal error: Only variables can be passed by reference in .../public_html/wp-includes/class-wp-customize-setting.php on line 90
