 * Hi,
 * when i installed the theme i received this error:
    PHP Fatal error: Call-time
   pass-by-reference has been removed in /var/www/antov/wp-content/themes/tarski/
   library/core.php on line 49
 * I fixed it by removing “&” before $matches in the mentioned line:
    preg_match(“/\\.[
   A-Za-z\d]+\$/”, $path, $matches);
