Hello,

Did you add any code related to post images? Try to disable Autoptimize temporarily and check it works or not.

Also, try to add the below code to the Customize > Custom CSS section to display it.

.has-post-thumbnail img.wp-post-image, .attachment-twentyseventeen-featured-image.wp-post-image {
    display: block !important;
}

pro-tip; you can disable Autoptimize on a per-request basis by adding ?ao_noptimize=1 to the URL.

if the problem is not there at that point, some autoptimize (re-)configuration might be needed to fix this. there are troubleshooting tips and info on how to exclude in the AO FAQ.

hope this helps debugging,
frank (ao dev)

Thanks, adding code helped!

Happy to hear that it worked!
