Can read php files

All the PHP files seem to have permission 000 (cannot be accessed by anyone), which causes a WordPress down and cannot be recovered.

Could you please help to recover by granting appropriate permission to user ‘pxiao’?

account id: #257958
$ cd /home/pxiao/
$ ls -l

I’ve sent the support request several time, though nobody responded!

Why nobody reply?
