non_descript

Thank you for the advice but it didn’t work. I also tried adding the image to #main and .wrapper. Which are the id and the style class for the div surrounding this area in all content types – posts, pages… I don’t know if I am explaining it clear. Just for debugging purposes I added a border around the div (#page-wrapper) and I can only see the top border of the element. I even tried adding the style to the html tag itself, again just to test it, and still no result. May be something is overwriting the style? Any ideas?

… and thanks for the Firebug advice I installed it and already helped me with some other issues I’ve been having. I will continue trying to debug this issue.

Thank You!!!
That did it.
I am posting the whole code for future reference – just in case.

<?php
/**
 * This file provides additional functions for sharko's theme.
 */

 /**
 * Returns a "Continue Reading" link in BG for excerpts
 */
function sharko_continue_reading_link() {
	return ' <a href="'. esc_url( get_permalink() ) . '">' . __( 'прочети <span class="meta-nav">&rarr;</span>', 'twentyeleven' ) . '</a>';
}

/*
 * Removes the get_the_exerpt filter
 */
function sharko_remove_excerpt_filter() {
   remove_filter( 'get_the_excerpt', 'twentyeleven_custom_excerpt_more' );
}
add_action( 'after_setup_theme', 'sharko_remove_excerpt_filter' );

/**
 * Adds a pretty "Continue Reading" link to custom post excerpts.
 *
 */

function sharko_custom_excerpt_more( $output ) {
	if ( has_excerpt() && ! is_attachment() ) {
		$output .= sharko_continue_reading_link();
	}
	return $output;
}
add_filter( 'get_the_excerpt', 'sharko_custom_excerpt_more' );
?>

Thank you!
I tried that but bumped into another problem. Now I don’t get the error but I got two “Continue reading ” links :). The first is as I want it and the second is the default. As if the old filter stays and both filters are called – first the one from the child theme then the default… Any help, plese!
Here is the code:

remove_filter( 'get_the_excerpt', 'twentyeleven_custom_excerpt_more' );
function sharko_custom_excerpt_more( $output ) {
	if ( has_excerpt() && ! is_attachment() ) {
		$output .= sharko_continue_reading_link();
	}
	return $output;
}
add_filter( 'get_the_excerpt', 'sharko_custom_excerpt_more' );

Probably the remove_filter didn’t work because the original filter is created in the parent theme’s functions.php which is loaded after the child theme?
