Thanks for your help guys but I found the solution 🙂

Just incase anyone may need it in the future:

Note: Before copy pasting, don’t forget to change somePrefix with any other prefix to avoid conflict with any other shortcodes.

Step 1: Make sure you have this filter in functions.php (If not, copy paste it there)

add_filter(‘wp_nav_menu_items’, ‘do_shortcode’);

Step 2: Use this snippet to return Author URL. Paste this in functions.php

add_shortcode( ‘somePrefix_author_url’, function() {

$author_link = get_author_posts_url( get_current_user_id() ); // original link
$without_protocol = trim( str_replace( array( ‘http://’, ‘https://’ ), ”, $author_link ), ‘/’ );
return $without_protocol; // returns author link without protocol

});

Step 3: Go to Navigation Menu and add Custom Menu Link and use [somePrefix_author_url] in the URL field and ‘My personal page’ or something in the Name field.

Step 4: Test the link from the front-end if it works.
