Hi, I need your help with the facebook share button. In some posts it does not work correctly, I see the message "page not found". Also I'd like to add a share box at a page, not only at a post. Please help me as soon as possible, because I have problem with the promotion of the site.

To resolve this issue please follow my instruction here:
1. Open functions.php file in /wp-content/themes/dw-focus/functions.php 2. Replace following code from line 412 to line 417 

$twitter_count = dw_get_twitter_count( $url );
 // //Twitter
 // $twitter_count = dw_get_twitter_count( $url );
 $facebook_count = dw_get_facebook_count( $url );
 $linkedin_count = dw_get_linkedin_count( $url );
 $gplus_count = dw_get_plusones_share_count( $url );

with:

$twitter_count = dw_get_twitter_count( get_permalink() );
 $facebook_count = dw_get_facebook_count( $url );
 $linkedin_count = dw_get_linkedin_count( get_permalink() );
 $gplus_count = dw_get_plusones_share_count( get_permalink() );

3. Replace following code from line 1104 to line 1105

// if( isset($json['result']) )
 return intval( $json['result']['metadata']['globalCounts']['count'] );

with:

return intval( $json['result']['metadata']['globalCounts']['count'] );
