Virtuemart cart not working
If for some reason in your browser the virtuemart cart (adding articles to your cart) does not work properly, in some browsers, troubleshooting can be hard.
First check if you have an jquery problems, you can do this via the console of your browsers to see if any jquery or javascript errors occur. If this is not the case, the problem could very well be the cookie domain settings. Go to your system settings and set the cookie domains empty. to check this you can go to your php settings and see the cookie domain values.
if this change does not work, you can delete the cookie domain lines in your configuration.php, but note that they will re-appear as soon as you update your system settings within joomla.

The article correctly points out the crucial role of browser compatibility and cookie settings in Virtuemart cart functionality. However, it could benefit from further elaboration on specific jQuery/JavaScript error types and how to interpret them. For instance, if the console shows a "TypeError," it indicates a problem with the data being passed or manipulated. A more detailed explanation of how to identify and resolve JavaScript errors specific to Virtuemart would be extremely helpful.
