Hello David!
I’ve removed that section at the foot of the page and the error in the console disappears. So, I will request the provider of the subscribe form script to fix it.
Anyway, I’ve just received this CSS code from plugin support and the problem with the booking form is solved:
.woocommerce #content div.product div.summary, .woocommerce div.product div.summary, .woocommerce-page #content div.product div.summary, .woocommerce-page div.product div.summary {
display: inline-block;
width: 60%;
box-sizing: border-box;
padding-left: 50px;
overflow: visible;
}
.woocommerce-product-gallery.woocommerce-product-gallery--with-images.images {
display: inline-block!important;
margin: 0;
}
Thank you very much
