Client Project - Validate Checker

I thought before i duplicated my template throughout Modx i went onto W3C online HTML5 Validator. I got 2 errors! (below)



1. Line 6, Column 26: Bad value [(site_url)] for attribute href on element base: Illegal character in path component.
Syntax of IRI reference:
Any URL. For example: /hello, #canvas, or http://example.org/. Characters should be represented in NFC and spaces should be escaped as %20.

2. Line 6, Column 33: Stray end tag base.

I'm going to look into these errors and update this post later...
