More than likely it is your browser changing the user-agent because it detects that the page might be better viewed in a different version of that browser. IE does this a lot and it causes a new session to be created. If you are running V2, you can try adding this to your config.local.php file:

fn_define('SKIP_SESSION_VALIDATION', true);

This will tell cs-cart not to detect user-agent or IP address changes to invalidate the session.

When I try adding this to your config.local.php file:

fn_define('SKIP_SESSION_VALIDATION', true);

the system inform error: Call to undefined function fn_define() in /home/fantas04/public_html/config.local.php on line 22

Please help us resole this. Thanks

tbirnseth, once more to the rescue! thanks!

Due note that this does break down some of the session security. But I don't believe the browsers would switch user-agents when that security was originally deployed. Now that most merchants do NOT allow users to store credit cards in their profiles, the risk of a session highjack is pretty low.

tbirnseth, hello again. Although I initially thought it worked, it still doesn't. Any other ideas?

The problem is reproducable when I click 'add to cart' for different products. After the cart has 1-2 products, it resets and gets back to the product you added latest.

Hello Tbirnseth

I just add line [color=#000088][size=2]if[/size][/color][color=#666600]size=2[/size][/color][color=#000000][size=2] define[/size][/color][color=#666600]size=2; according you and clear cache but we can not do it which checkout .[/size][/color]

What can we do ? Thanks for your support . we are waitting information .

All best wishes /

Sorry, don't have any other suggestions… From what you describe, the session is being reset (causing the cart to be lost). The code I provided is the only thing in the cart that will reset the session unless the IP address also changed. Is this a mobile device?

no…3 different desktop pcs, also different browsers…

Suggest you contact the helpdesk…

Message from help desk to me a while back on same issue on V3


I should tell that the Internet Explorer 11 appeared in November 2013, while v.3.0.6. appeared much earlier. Unfortunately, we cannot guarantee that it will work correctly in the newer browser versions.


OK . Not problem when you Disable plug in Required products …
