404 on blog posts

Hi again..

I've installed Perch and the blog app and most of it seems OK although one thing is puzzling me. I can create posts fine and they show up in the latest feed, however if I try and go to the post itself it seems to want to strip the WDD4 out of the URL. Example

https://blablahexampleweb.org/wdd4/blog/

If you click any of the items in the list it wants to go to (eg) https://blablahexampleweb.org/blog/post.php?s=2014-07-06-after-permissions-test (i.e missing the WDD4).

Now nothing relating to Perch nor the blog sits in the site root so I can only assume that it is aiming for the site's HTTP Host

SUMMARY INFORMATION

PERCH_LOGINPATH: /wdd4/perch PERCH_PATH: /home/ghubba02/htdocs/wdd4/perch PERCH_CORE: /home/ghubba02/htdocs/wdd4/perch/core PERCH_RESFILEPATH: /home/ghubba02/htdocs/wdd4/perch/resources Image manipulation: GD PHP limits: Max upload 7M, Max POST 7M, Memory: 90M, Total max file upload: 7M Resource folder writeable: Yes HTTP_HOST: https://blablahexampleweb.org DOCUMENT_ROOT: /home/ghubba02/htdocs REQUEST_URI: /wdd4/perch/core/settings/diagnostics/ SCRIPT_NAME: /wdd4/perch/core/settings/diagnostics/index.php

I tried updating the Live Domain field on my account (as it's missing the WDD4 where it resides) but now when I go to login to the Perch CRM I get the error

"Sorry, your license key isn't valid for this domain. Log into your Perch account and add the following as your live or testing domain: blablahexampleweb.org"

Thanks again in advance
