Only few featured images loading

Hello,

Are you referring to the ones that are a white squares? Or for Mathias and Jacob?

For the white squares, Not sure but I would look at your plugin settings with Speed Booster Pack. It looks to be replacing the images with a 1×1 gif. (https://rentrafik.dk/wp-content/plugins/speed-booster-pack/inc/images/1×1.trans.gif)

Thank you! I was referring to the white squares. It was a Lazy load feature in the Speed Booster Package that was causing the problem – it is now disables and the images loads. Thanks!
