my site is created on WordPress
I put in the site a callback code
and he partially changed the layout of my site
This problem occurred due to
but without this code the form does not work
the site has the following library
<link rel='stylesheet' id='wp-block-library-css' href='/wp-includes/css/dist/block-library/style.min.css?ver=5.0.3' type='text/css' media='all' /> <link rel='stylesheet' id='wp-block-library-theme-css' href='/wp-includes/css/dist/block-library/theme.min.css?ver=5.0.3' type='text/css' media='all' />
What do you advise me to do?
