Can't View Profile

Everytime I try to Navigate to the Profile section, it says it doesn't exist.
I tried to create a new member, and navigate there, no go.

This was happening even on my local machine, and I have no idea what the problem is.

It apparently can't resolve website.com/membername

Any solutions? 

re-upload htaccess, maybe it will help you

I was missing

ReWriteBase /

from the .htaccess file
It works now!

This line needs to be placed below

RewriteEngine on

[Just in case anyone else gets this error]
