[Closed] Warning on posting a Woocommerce review

I've been getting:

Warning: Invalid argument supplied for foreach() in /wp-content/plugins/woocommerce-multilingual/inc/class-wcml-comments.php on line 72

Warning: Cannot modify header information - headers already sent by (output started at /wp-content/plugins/woocommerce-multilingual/inc/class-wcml-comments.php:72) in /wp-includes/pluggable.php on line 1219

The solution is an additional check:

[code]
if ( $ratings && is_array($ratings) ) {
foreach ( $ratings as $rating => $count ) {
$average_ratings_sum += $rating * $count;
$average_ratings_count += $count;
}
}

[/code]
