After installing free ssl site says cert is not valid [Resolved]

After installing the free SSL server surfing to my site says the cert is not valid. https has the red line through it.

Followed this guide: Knowledgebase - Powered by Kayako Help Desk Software
Why would the say to install the cert as personal and not as website?

Any help would be great.

Solved my issue. Comodo Please update your guide above.
