Just 3 plugins activated for the moment:

Fatal error: Call to undefined method WooCommerce::add_error() in xxx/wp-content/plugins/paymill/lib/integration/woocommerce.inc.php on line 7
I’ll need to check your issue on your site, as I cannot reproduce your error on my server. Could you send me FTP/WP-Admin data to info@straightvisions.com ? I’ll check that issue today then.
Kind regards,
Matthias
Will be fixed in v1.9.1
Hotfix:
replace old code of function paymill_woocommerce_errorHandling in file /wp-content/plugins/paymill/lib/integration/woocommerce.inc.php with
function paymill_woocommerce_errorHandling($errors){
if(!defined('PAYMILL_WOO_NOTICES_SENT')){
foreach($errors as $error){
wc_add_notice('<div class="paymill_error">'.$error.'</div>', 'error' );
}
define('PAYMILL_WOO_NOTICES_SENT',true);
}
}
