How to Fix 403 Forbidden Error for Your Website

Today i opened my website by browser and found this problem:


You don't have permission to access / on this server.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

This problem surprised me, because i have done nothing with my website, however, why this problem occured?

To fix this problem, i checked my web host and find the reason:

Becacuse my website was suspended by bandwitdh overused.

So i contacted my web host server and increased my web host bandwidth, and this problem fixed.
