Changing author page address

By using .htaccess, this could be easily done.

But you have to search it from your side.

Sorry
However, I searched, I didn’t get anything. Can you help?
I don’t know how to code it!

Here is a basic .htaccess rewrite template. You need to alter it for your configuration. One wrong character can bring down your entire site, so be ready to restore the original working condition. Sometimes your error and access logs will give a clue to what went wrong. I’m not responsible if you don’t confirm the correct syntax for yourself. This is just a template to point you in the right direction.

<ifmodule mod_rewrite.c>
	RewriteEngine on
	RewriteBase /
	RewriteCond %{REQUEST_URI} ^/user/	[NC]
	RewriteRule ^/user/(.*) /author/$1	[L]
</ifmodule>

I’ve found another code myself.
Anyway, thank you very much for your help.

<?php

add_filter(
    'init',
    create_function(
        '$a',
        'global $wp_rewrite;
        $wp_rewrite->author_base = "the name";
        $wp_rewrite->flush_rules();'
    )
);
// Put Your ideal slug instead of "the name"

?>
