With no form action at all I get the following error:
Warning: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/websitename.com/Connections/ProductsDb.php:9) in /Applications/MAMP/htdocs/websitename.com/Prod_results.php on line 226
from Remote server:
The cart is empty
Also tried deleting only the php, but both local and remote servers showed: The cart is empty.
