Plesk default web page opens instead of WordPress page

Symptoms

WordPress instance was installed and configured for the domain;

Default Plesk or a custom web page opens instead of the WordPress page.

Cause

The file index.html is in the domain's document root.

By default, the list of defined index files (Subscriptions > example.com > Apache & Nginx Settings in Linux, Subscriptions > example.com > IIS Settings in Windows) start with index.html as the first in priority. Whenever both index.php and index.html are in the document root, index.html is served.

Resolution

1. Log into Plesk;
2. Go to  Domains > example.com > File Manager;
3. Open domain's document root directory, for example, httpdocs:
   
4. Rename index.html or delete it.

Or exclude index.html from the list of index files(Linux) or Default documents(Windows):

1. Log into Plesk;
2. Go to Domains > example.com > Apache & Nginx Settings (Linux) or Domains > example.com > IIS Settings (Windows)
3. Enable custom values for index files or Default documents and remove index.html from the list
