Instale Facebook Mod, cuando entro a un tema me aparece:

Alguna Solución?

Supongo que lo has instalado manualmente, pero probablemente has dejado un espacio en blanco antes o después de algún <?php o al final en ?>

Repasa los ficheros .php que has editado y serciórate de que esté bien ese detalle. Luego limpia la caché.

Si, tenia un espacio en blanco antes de ?> en function_display.php
Pero, el problema persiste.
Estas son las lineas:
1362 $flag_img = (!empty($flags[$user_flag]['image'])) ? '<img src="' . $phpbb_root_path . $config['flags_path'] . '/' . $flags[$user_flag]['image'] . '" alt="' . $flag_text . '" title="' . $flag_text . '" />' : '';
1363 $flag_img_src = (!empty($flags[$user_flag]['image'])) ? $phpbb_root_path . $config['flags_path'] . '/' . $flags[$user_flag]['image'] : '';
}
}
?>

¿Has comprobado todos los archivos que tuviste que editar?

¿Has limpiado la caché?

Me olvide de aclarar, antes de instalar Facebook Mod instale Seo Mod.

Esta es la Linea 1858 de viewtopic.php
1858 if($posts_per_day >= $level_avg_ppd)
{
$level_hp_percent = floor( (.5 + (($level_user_ppd - $level_avg_ppd) / ($level_bonus_redux * 2)) ) * 100);
}

La 1959:
else
{
$level_posts_for_next = floor( pow( 10, pow( $level_level, (1/3) ) ) );

$level_exp = $user_cache[$poster_id]['posts'] . ' / ' . $level_posts_for_next;
1959 $level_exp_percent = floor( ($user_cache[$poster_id]['posts'] - $level_posts_for_this) / max(1,($level_posts_for_next - $level_posts_for_this)) * 100);
}

y en Functions.php:
// application/xhtml+xml not used because of IE
4269 header('Content-type: text/html; charset=UTF-8');

4271 header('Cache-Control: private, no-cache="set-cookie"');
4272 header('Expires: 0');
4273 header('Pragma: no-cache');

return;
}

Pues entonces el problema podría ser algún archivo editado para aplicar el SEO MOD. Ese son muchos archivos a editar... puede ser un fastidio comprobar todos los inicios y finales de cada fichero, pero es que creo que ese error suele deberse a dejar algún espacio en blanco justo antes de <?php o justo después de ?>

Entonces, Reviso esos tres archivos para ver si tienen algun espacion antes o despues de ?>

No hay caso...
Busque en los tres archivos y borre las lineas en blanco antes del ?> limpie el cache, y nada...
