That is not a problem but just a warning. It is caused by WP_debug

Please remove that on wp-config.php

switch from TRUE to FALSE

Thanks

Try to modify line 49 on that file, replace with this:

$tag_out = '';
if( $tags ){
 $num=count($tags);
 $i=0;
 foreach($tags as $tag):
  if(++$i === $num){
     $tag_out .= $tag->name;
  }
  else {
     $tag_out .= $tag->name.', ';
  }
 endforeach;
}

Yes, send me so I can fix directly

Thanks
