Forum keeps redirecting to homepage

[Ben]

These are correct I believe.

Admin Panel -> Configuration -> Site Details -> Board URL

You'll probably find that it will be set to northeastbuses.co.uk change it to http://www.northeastbuses.co.uk/forum

EDIT: Does this happen on the default theme? There is a jquery file missing.

Acp -> Templates & Themes -> Templates -> Your Theme -> Headerinclude

Find:

<script type="text/javascript" src="http://northeastbuses.co.uk/template/jquery-1.4.2.min.js"></script>

Try removing that.
