“Warning: Missing argument 2 for wpdb”

Dupa ce am facut update-ul la Wordpres 3.5 m-am trezit cu o eroare in footer-ul blogului (footer.php) ce returna urmatorul mesaj:

Warning: Missing argument 2 for wpdb::prepare(), called in /wp-content/themes/inove/footer.php on line 50 and defined in /wp-includes/wp-db.php on line 990

Dupa cateva minute de cautari am gasit o solutia, pe care am adaptat-o, si fost aceea de a inlocui linia 50 din footer.php (/wp-content/themes/inove/footer.php):

$post_datetimes = $wpdb->get_row($wpdb->prepare(“SELECT YEAR(min(post_date_gmt)) AS firstyear, YEAR(max(post_date_gmt)) AS lastyear FROM $wpdb->posts WHERE post_date_gmt > 1970”));

cu urmatoarea linie:

$post_datetimes = $wpdb->get_row($wpdb->prepare(“SELECT YEAR(min(post_date_gmt)) AS firstyear, YEAR(max(post_date_gmt)) AS lastyear FROM $wpdb->posts WHERE post_date_gmt > %d”, ‘1970’));
