Deploy Laravel on 000webhost- upload image file error

I have just deployed my laravel project to 000webhost, everything works fine, but when I upload image file to change user's avatar it returns empty string, only input file type, the others input works normally. This only cause on 000webhost, my local works normally, so I don't think my code have wrong. This error cause when I upload image file. (You can test it in my website "vmusocial.000webhostapp.com") My profile controller
