How to change default page in plesk

Question

How can I change Plesk default page. How can I change page which is set on http://xx.xx.xx.xx where is default Plesk page.

Answer 1

It should be located in /var/www/vhosts/.skel/0/httpdocs/index.html, but that will only apply to any new domains you create.
You may also want to edit /var/www/vhosts/default/htdocs/index.html (The default file served when there is no vhost defined for a domain)

Answer 2

Exactly, /var/www/vhosts/.skel/0 is where Plesk gets its "skeleton", hence the name, to create default welcome pages and directory contents for newly installed domains. You may want to remove contents from there such as the test cgi scripts, and add your custom page to serve as the Index.
