in it, but it isn’t working. I’ve also edited my Theme Functions php with the desired featured image size, regenerated my thumbnails and everything – to no avail. If someone could walk me through an easy way to resolve this, I would appreciate it.
I visited your shared site and it seems you are using Jetpack plugin on your site so could you please try temporary deactivating its Photon module on your site?
This jetpack photon module is not updating the images stored on wp.com so to resolve the issue either disable this module or update the images on wp.com by contacting jetpack support team.
Sorry to reach out again in the same thread, but I disabled the photon, regenerated thumbnails, and still, nothing solved my image issue. I have since turned the photon back on.
