I am having this headers issue. If I add an new product, it gives me this error:

Warning: Cannot modify header information - headers already sent by (output started at /home/exophora/public_html/e-store/includes/languages/english/index.php:60) in /home/exophora/public_html/e-store/includes/functions/functions_general.php on line 41


This error occur whenever I click a link to a category containing the item. However, if the category is empty it is working fine.

Will somebody please help me?

thanks
