Getting 403 error

I am getting 403 error, Access Forbidden in my WordPress site.

Here is the address: https://www.sportsroar.com

Here is what i tried so far:

1) Delete the .htaccess file, then tried the site. Delete it and upload again
2) Disable all the plugins.
3) Delete all the codes from .htaccess, kept it blank.
4) Checked the file permission

I have read many posts here regarding the same topic but could not solve it.
Any help??? Thanks in advance.
