This seemed to be a conflict with W3 Total Cache with JS minify enabled.

I’ve just discovered that the issue (at least my issue) relates to the Photon extension in Jetpack. Deactivating Photo fixed my images.

I’m having the same issue too. Everything was working fine and then all of a sudden the featured image thumbnail are the original image size.

Has anyone found a solution for this?

Thanks JowiM! Worked perfectly!
