@mikulski : It’s a little strange why it’s not working on your site. We tested on our server and it’s working fine. So, for quick fix, please add the following CSS in “Appearance => Customize => Additional CSS” box:
body .is-layout-flex {
display: flex;
flex-wrap: wrap;
}
figure.wp-block-gallery.has-nested-images {
align-items: normal;
}
Note: Also, I see one issue in your Custom CSS code which you currently have. Please search for this CSS in your Custom CSS box:
.singular-content-wrap .entry-header {
padding: 0 0 10px;
/*background-image: url(https://mikulski.rocks/wp-content/uploads/2022/07/headerbgmoface.webp)*/;
}
There you can see that you have commented out the background image but the closing comment tag is before the semicolon. It should be after the semicolon like below:
.singular-content-wrap .entry-header {
padding: 0 0 10px;
/*background-image: url(https://mikulski.rocks/wp-content/uploads/2022/07/headerbgmoface.webp);*/
}
