Error text on top of page

[rasmusvaino]

When i visit my page then in the header there is this text : Deprecated: strstr(): Passing null to parameter #1 ($haystack) of type string is deprecated in /data01/virt120083/domeenid/www.arvutipunkt.ee/htdocs/wp-content/plugins/woocommerce/includes/wc-page-functions.php on line 139

If i am logged in WordPress and im viewing my site then it shows nothing. But when im logged out it shows that error.
How can i fix this?
