Don’t know if anyone is interested but I solved this by removing a conflicting directory from my website root.
Hooray – I solved the problem. My forums are in the /forums/ (virtual) directory – however that directory still existed on my server because that’s where the forum was when I ran the standalone version of bbpress – and so that must have been conflicting. Move the directory and all is good again.
You can close this now 🙂
To follow on from this I have noticed that if I click one of the admin links (close topic for example) that the link just reloads the topic with the query parameters in the url and neither redirects to the proper location or perform the action.
I have tried resetting my permalinks and then setting them back but that makes no difference.
that’s very interesting. No idea why the feed won’t load – it works fine if you access it directly :S
I don’t think it’s a server thing – but I’ll dig deeper.
Thanks for the pointer.
I created that function. You need to add it to your themes functions.php file
I would be happy to give you access to my test setup if you want to see it for yourself?

That’s the whole point – I didn’t set it to 0. I was trying to set the number smaller to see what happens when topics get split into pages (which incidentally doesn’t seem to happen).
To reproduce enable WP_DEBUG and try saving a setting in the bbpress control panel. I got all sorts of errors when I did that.
In addition I have not yet been able to edit a setting. If I disable WP_DEBUG then the page refreshes when I press save but the settings do not get updated.
Please note I am using WP3.3 nightlies – so perhaps something has changed there.
I disabled WP_DEBUG in wp-config.php and resaved and the errors went away. Still, I always develop with WP_DEBUG enabled so it would be good if I could test things without getting errors.
Thanks for the tip off – I found the rogue code!
aaaand – I got it.
Was missing a style – I got all the bbpress template ones and missed the default one that is built into the plugin
easier than I imagined.
function bm_bbp_no_breadcrumb ($param) {
return true;
}
add_filter ('bbp_no_breadcrumb', 'bm_bbp_no_breadcrumb');
How would you like to send me my dollar? 
Now if only I could work out why this isn’t working properly – https://bbpress.org/forums/topic/remove-default-template-styles?
I had a feeling you would say that. I was hoping there was a way of overriding the function/ some include file somewhere. Oh well – thanks for clarifying
