90% of the time when I try to add to cart on the product page I get this error -
“Parameter Missing or Invalid: Required parameter missing or invalid: items“
my sites url - www.mycarkeyz.com
please help!
Works fine for me in chrome latest.
Others need to be able to reliably and consistently reproduce the bug in order to even begin to figure out what’s going on.
So you would have to find the pattern then give EXACT reproduction steps and detail including exact urls. Don’t just link to your website when having a problem don’t make others dig around link to exact pages.
This could be anything from just not letting the page load properly to your browser cache needing to be cleared.
Things to try
- Clear your browser cache
- If you’ve recently customized the theme undo it or disable it
- If you’ve recently installed apps, uninstall or disable it
Beyond that it would be an open ended debugging problem someone would have to invest time on.
