Okay - I am seeing this error after a VSADMIN update to the Ecommerce Plus PHP v6.8.4
I am at a loss and can not figure it out ...
Warning: Cannot modify header information - headers already sent by (output started at /home/sunriset/public_html/proddetail.php:735) in /home/sunriset/public_html/vsadmin/inc/incproddetail.php on line 803
Hi, the most common cause is a empty space at the very top of one of the include files, I see from your other post that you needed to edit the vsadmin/db_conn_open.php for this update, can you check that there are no blank spaces, its best to use a pure html editor like notepad++ or html-kit as the space is sometimes hidden from other edtiors.
However, I am noticing when entering item into the cart the popup window is not viewing correctly. The background is not solid and it expands to the full width of the page. I have moved the CSS folder to the server.
