WordPress Theme is_front_page() function error

Try like this.

<?php

// Check if it's the front page
if ( is_front_page() ) {
    // Content specific to the front page
    echo '<h1>Welcome to My Website!</h1>';
} else {
    // Content specific to blog posts (assuming posts are displayed on index.php)
    // Use the WordPress loop to display posts
    if ( have_posts() ) {
        while ( have_posts() ) {
            the_post();
            // Display post content here (title, excerpt, etc.)
        }
    } else {
        // Handle the case where there are no posts
        echo '<p>No posts found.</p>';
    }
}

?>

That deprecated notice is not directly the result of using is_front_page(), rather it’s some sort of knock on effect. The fact the notice occurred in functions.php is not useful information. You’d need a debug backtrace to learn the true root source of the deprecated notice. It’s likely due to theme or plugin code that was executed as a result of your use of is_front_page(), but your use itself is not in error.

Thanks, @yaqub16 and @bcworkz , for your assistance with this issue. I’ve decided to create a separate file instead of continuing with the changes in index.php
