Warning: Add-Headers tried to append its headers to the headers list, but the header list had already been sent to the client by other code. This is not a problem caused by the Add-Headers plugin. Moreover, the Add-Headers plugin can do nothing about this issue. Please investigate which plugin or theme sends the headers earlier than what is expected. in /home/customer/www/thehotelcloud.com/public_html/wp-content/plugins/add-headers/add-headers.php on line 95 Hotelcloud | Sign up
