The ideal situation is to install your Tiki instance to serve the root of a domain or sub-domain

• example.org/tiki-index_raw.php
• wiki.example.org/tiki-index_raw.php

Installing in a sub-directory like this

• example.org/wiki/tiki-index_raw.php

• Review your settings for CalDAV and CardDAV.

• feature_html_head_base_tag (Add base tag in the HTML head section. The base tag specifies a default address for all links on a page.)

• Tiki Installation Guide
• Path structure
• File and Folder permissions
• Single Sign On for sub-domains
