using JS 3.8.0 since today. After klick on "in den Warenkorb" i get the following message:
"Warning: Cannot modify header information headers already sent by (output started at /homepage/XXXXXXXXX/htdocs/joomla/components/com_jshopping/lang/de-DE.php: 1) in /homepage/XXXXXXXXX/htdocs/joomla/components/com_jshopping/controllers/cart.php on line 20"
The same comes up on click to "zur Kasse".
Is there any chance to solve this problem?
