# Theme Check problem

* I am creating my first WP Theme and I would like to upload it to wordpress.org.
That’s why I use, as recommended, Theme Check Plugin.
* I resolved other issues, except these two.
1. **REQUIRED: The tags can
only contain a call to wp_title(). Use the wp_title filter to modify the output**
* I understand that is related to title tag in header.php, am I wrong?
This is
my header:
* ```
<!doctype html>
<!-- paulirish.com/2008/conditional-stylesheets-vs-css-hacks-answer-neither/ -->
<!--[if lt IE 7]> <html class="no-js lt-ie9 lt-ie8 lt-ie7" <?php language_attributes(); ?>> <![endif]-->
<!--[if IE 7]> <html class="no-js lt-ie9 lt-ie8" <?php language_attributes(); ?>> <![endif]-->
<!--[if IE 8]> <html class="no-js lt-ie9" <?php language_attributes(); ?>> <![endif]-->
<!-- Consider adding a manifest.appcache: h5bp.com/d/Offline -->
<!--[if gt IE 8]><!--> <html class="no-js" <?php language_attributes(); ?>> <!--<![endif]-->
<head>
<meta charset="<?php bloginfo( 'charset' ); ?>" />
<!-- Always force latest IE rendering engine (even in intranet) & Chrome Frame -->
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><title><?php wp_title( '|', true, 'right' ); ?>
```
* What is wrong with it?
* 2. **REQUIRED: screen_icon() found in the file class-tgm-plugin-activation.php.
Deprecated since version 3.8.**
* ```
Line 381: screen_icon( apply_filters( 'tgmpa_default_screen_icon', 'themes' ) );
Line 1584: screen_icon( apply_filters( 'tgmpa_default_screen_icon', 'themes' ) );
```
* I understand that, but I don’t know with what should I replace it?
* I am really greatfull for your potential answers.

* Hi,
* If you are using a theme based on “underscores” theme, when you trying to check
your theme using “Theme-Check” plugin you will see this message:
* `The tags can only contain a call to wp_title(). Use the wp_title filter
to modify the output`
* To fix this problem go to inc/extras.php file and find this:
* ```
if ( ! function_exists( '_wp_render_title_tag' ) ) :
/**
* Title shim for sites older than WordPress 4.1.
*
* @link https://make.wordpress.org/core/2014/10/29/title-tags-in-4-1/
* @todo Remove this function when WordPress 4.3 is released.
*/
function themeslug_render_title() {
echo '<title>' . wp_title( '|', false, 'right' ) . "\n";
}
add_action( 'wp_head', 'themeslug_render_title' );
endif;
```
* Replace it with:
* ```
if ( ! function_exists( '_wp_render_title_tag' ) ) :
function themeslug_render_title() {
?>
<?php wp_title( '|', true, 'right' ); ?>
