Images is corrupted

After updating to the full version of UNA 11, my website images just gets corrupted once they are uploaded. 

Videos can't be uploaded and nothing related to media works! 

I made sure I updated all my APPS after I updated to UNA 11 yet I have all this errors to deal with and my members asking questions about what has happened to their images and profile photos. 

I'm extremely disappointed cuz I thought UNA is past this stage of uncertainty!

I waited so long to update cuz I didn't want the update to affect my site but now the very same thing happened!
