Yup.
Replicated.
Edit: It's because the link off the banner is to "/index.php" without declaring the whole path. For example, if you click on the banner from the main forum page, (i.e. not from a board), it will work fine as "
www.noddegamra.co.uk/forum/index.php" actually exists, compared with "
www.noddegamra.co.uk/forum/feedback/www-noddegamra-co-uk-404-not-found/0/index.php" for example which does not.
Edit2: The offending piece of code:
<a href="index.php">
<img src="http://www.noddegamra.co.uk/forum/Themes/nodd_default/images/banner_v2.gif" alt="Noddegamra Forum" title="Noddegamra Forum" />
</a>
Should be ammended to:
<a href="http://www.noddegamra.co.uk/forum/index.php">
<img src="http://www.noddegamra.co.uk/forum/Themes/nodd_default/images/banner_v2.gif" alt="Noddegamra Forum" title="Noddegamra Forum" />
