Issue: Twitter is displaying summary cards instead of large image summary cards. I have the large image summary card code saved in my header.php file, and can see that code on the desired pages, but there is also a summary card code appearing that I cannot locate that seems to be trumping the large image code.
URL affected: All WordPress “post” URLs on my site are affected, however, here is an example: http://milehighsports.com/rockies-adding-another-all-star-ahead-of-trade-deadline/
Troubleshooting steps tried already: I’ve searched every php file for the code and cannot find it. I’ve had my developer/support look for the code as well, and they cannot find it.
We believe it is tied to the Twitter plugin. We recently deactivated the Yoast SEO plugin and had to activate the Twitter plugin in order for cards to appear. (Cards were appearing prior to using either Yoast or Twitter plugin, simply by having the card code in the header.php file.)
