PHP silence is golden

I can’t updating any plugins and I can’t reaching images. there is an error I took while I am trying to update any plugin is here :

Güncelleme ba?ar?s?z: <?php/*Silence is Golden*/?><?php/*Silence is Golden*/?>{“success”:true,”data”:{“update”:”plugin”,”slug”:”all-in-one-seo-pack-pro”,”oldVersion”:”S\u00fcr\u00fcm 4.1.0.2″,”newVersion”:”S\u00fcr\u00fcm 4.1.1″,”plugin”:”all-in-one-seo-pack-pro\/all_in_one_seo_pack.php”,”pluginName”:”All in One SEO Pro”}}

Update failed error. I guess I have broke or deleted some lines or files which includes php silence is golden. How can i get this main files back?
