Backup not restore (internal server error)

Hi

I am using erpnext hosted free account.
Now i want to restore its backup on my local setup of erpnext.
after creating a new site on my local setup i have tried to restore backup from my hosted erpnext account. DB is restored but it is showing Internal Server Error when i am trying to access it via browser. (localhost:8000)

What do you see in your error logs? What kind of setup are you using?

Error logs are empty.
I have tried multi tenant setup as well as single setup.
I have installed erpnext as production setup and before restoration it was
working fine.
