want full width featured image thumbnail with post excerpt option

Hi there,

Any chance you can link us to the site in question?

You can edit the original topic and use the private URL field.

Let me know :)

My site URL is https://blogginglift.com/blog/

Try removing this CSS from Additional CSS:

@media (min-width: 769px) {
    .post-image-aligned-left .post-image img {
        max-width: 300px;
    }
}
