The site is https://www.thepietasters.com. It is designed using Wordpress. I have the Twitter plug-in as well as the Yoast SEO plug-in installed. The problem I have is that when I added code to the theme header.php, it took that image, description, etc. and applied that to the Twitter Cards for other pages on the site. I don’t want that to happen.
In comparison, the Card Validator displays the featured image and description correctly for subpages and posts. Below is an example of a subpage Twitter Card:
Where can I add code to configure a Twitter Card for the main site? Or is there something else I need to do? Thanks in advance for any suggestions.
