Redirect old subdomain to new subfolder/subdirectory

If your host as C-Panel, you should be able to make a permanent 301 redirect from there.

I am using 1and1 hosting, which does not use cPanel, unfortunately.

Here is a very simple way to jump to a subfolder.
Open a simple text editor.
Paste in this code:

<?php
/**
* Jump to subfolder
*/
header (“Location: https://www.moneydolist.org/wordpress/&#8221;);
?>

Change the http: link text to match your site.
Save as index.php
Use an FTP app to place this new file in your primary domain folder.

Simple, no?
