I keep getting card invalid on just random customers. Can anyone help?
I keep getting calls from customers that when they checkout online they are getting card invalid. They have called their banks, clear cookies, tried different browsers, ugh!! Someone. Help.
Random issues are sometimes the most difficult to resolve. Please understand that Community is not the same as Tech Support or Customer Support - you may need someone from Tech Support to take a look at your site setup and log files. Sometimes un-publishing and re-publishing your site clears up unusual issues. A good place to check for system issues is here - if there's a problem with Square's production system, they will post comments there.
