"Warning: Cannot modify header information..."

"Warning: Cannot modify header information..."

Hi,

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?

Aw: "Warning: Cannot modify header information..."

save file
components/com_jshopping/lang/de-DE.php
as utf-8 without BOM (use notepad ++)

---

Aw: "Warning: Cannot modify header information..."

Wow...it works!

Thank's a lot!!!
