I noticed today that the featured images for all of my posts published since May are not right. Those published before that time are fine and have the correct dimensions and so I cannot work out why the recent posts look like this. It is especially noticeable on a mobile device.
I haven’t made any changes to the settings recently – at least to my knowledge – so I am a bit puzzled by this development.
Could you take a look and see why this might be happening?
I removed the custom size settings and the problem is now resolved. Seems strange that this only affected a handful of posts though. Does this mean that setting a custom-sized featured image no longer works with WordPress?
