Showing home page but at the title it shows PAGE NOT FOUND - php

Question

I have developed a wordpress theme. There are 2 pages HOME and ABOUT US. For home page I use index.php and for about us page I used page.php template. But when I click on home page it shows the title "page not found".
And I create a page named HOME then it is showing page contents which I posted in Home page but I need to show contents of index.php. (for example in index.php I have a slider. and I have created a page named "Home". When I click on home tab it is showing the contents that I posted on home page, NO SLIDER IS SHOWING)
Here is the site admission247.com
my page.php code
<?php if (have_posts()) : ?>
<?php while (have_posts()) : the_post(); ?>
<div class="page_content">
<?php // echo '<br/><br/>'; ?>
<?php the_content(); ?>
</div>
<?php endwhile; ?>
<?php endif; ?>

Answer 1

It's difficult to tell without seeing the code.
Here is a snippet of code I use for my header.
<title><?php
global $page, $paged;
wp_title("«", true, "right");
bloginfo("name");
$site_description = get_bloginfo("description", "display");
if($site_description && (is_home() || is_front_page()))
echo " « $site_description";
if($paged >= 2 || $page >= 2)
echo " « " . sprintf(__("Page %s", "h18"), max($paged, $page));
?></title>
If you can, post as much code as you can. It will help others understand your problem more.

YOUR_try this
functions.php
function site_wp_title( $title, $sep ) {
global $paged, $page;
if ( is_feed() )
return $title;
// Add the site name.
$title .= get_bloginfo( 'name' );
// Add the site description for the home/front page.
$site_description = get_bloginfo( 'description', 'display' );
if ( $site_description && ( is_home() || is_front_page() ) )
$title = "$title $sep $site_description";
// Add a page number if necessary.
if ( $paged >= 2 || $page >= 2 )
$title = "$title $sep " . sprintf( __( 'Page %s', 'YOUR_SITE' ), max( $paged, $page ) );
return $title;
}
add_filter( 'wp_title', 'site_wp_title', 10, 2 );
header.php
<title><?php wp_title( '|', true, 'right' ); ?></title>
