Call-time pass-by-reference error.

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);
