Hi arturfrolov727,

Thanks for your patience.

The problem is related to the long processing of the request to the database and after 5 seconds of the request the page is restarted. To increase the request waiting time, you need to add the following code to functions.php file in the Child theme.

add_filter( 'woodmart_pjax_timeout', function(){
	return 10000;
} );

Regards,
