URL in question www.kiteprint.com
This is a shopify website, and I have tried two alternate methods which still will not allow me to validate my Twitter Cards.
Manually adding a ‘liquid snippet’ file which lists the appropriate meta tags.
Using a Shopify Twitter Card App which displays the following meta tags once generated…
Example Product Page to view page source and check meta
I simply get the error message ‘warn: no meta tags found’
Any help on this one would be greatly appreciated!
