This was the default home-page of ki-leierbud.lu in the new Almalinux 9.6 Server hosted by Visual Online.

To replace the default home-page by a custom webpage I used the recommended website builder Sitejet :

I selected the Academix theme template to start with a first trial :

First Attempt – Upload Fails Due to File Size
The initial attempt to upload the image above failed because the file size exceeded 2 MB.
The PHP settings in Plesk were already configured to allow up to 64 MB, but WordPress still enforced a 2 MB upload limit.
ChatGPT pointed out that in such cases, a .user.ini file is required in the root directory of the WordPress installation to override the default behavior — especially when PHP is running in FPM (FastCGI Process Manager) mode, which is common in Plesk environments.
Using the “+” button in the File Manager, I created a new .user.ini file and added the following content:
upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300

Customized Home Page
To install a customized minimal web Homepage allowing to test the correct working of the WordPress REST API, I removed all the files in the “home directory > httpdocs” folder, except the index.html file. I replaced the content of this file with the following code :
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>KI-Léierbud</title>
<style>
body {
font-family: sans-serif;
padding: 40px;
background-color: #fdfdfd;
line-height: 1.6;
}
h1, h2, p {
margin-bottom: 1em;
}
a {
color: #0055cc;
text-decoration: none;
}
a:hover {
text-decoration: underline;
}
</style>
</head>
<body>
<h1>Welcome to My New Site KI-Léierbud!</h1>
<h2>Test the WordPress REST API</h2>
<p><a href="https://admin.ki-leierbud.lu/archives/244">Table of Content</a></p>
</body>
</html>
Here is the result :

The WordPress REST API is working as expected. Now it’s time to create a well designed Home-Page.
