What is wrong in this

wordpress

#1
  1. http://envato.d.pr/f4Zq/2luU9yub - from this reviewer and

  2. all home_url() must include a trailing slash such as home_url(‘/‘) - from other reviewer

href=’<?php echo esc_url( home_url('/') ); ?>’>


#2

You should sanitize the URL:

echo esc_url( home_url('/') )
