Hi,

I was trying to check the validity of my HTML for my Vanilla site using W3C's HTML checker the other day when it came back with a 404. It showed a 404 on any page I tried in Vanilla.
When looking at the site using a browser all the pages download fine. I decided to check the http headers in firefox using the Web Developer toolbar when I noticed that it said the following:

http://www.riskcollective.com/community/

How can it show a 404 yet download correctly - I'm so confused!! I obviously need to get this fixed otherwise the site won't get indexed by search engines.

The Vanilla installation is sitting inside a Wordpress installation. I'm using friendly urls in Vanilla and pretty permalink structure in WP.

Does anyone have any ideas??

Thanks,
Oli

oops.. Sorry I missed off the last line of that header when I copied/pasted it, which said....

Just found a couple of forum topics relating to this:

http://bbpress.org/forums/topic/strange-404-report-i-firebug
http://wordpress.org/support/topic/127302?replies=3.

It seems to be a conflict between wordpress permalinks and the vanilla friendly urls htaccess file. Not sure how to fix this one.... :-|

Anyone have any ideas??

You might be able to overwrite the 404 with a 200, try adding this inside conf/settings.php:header("HTTP/1.1 200 OK");

This might be something related to this: http://wordpress.org/support/topic/122089

Doh - spanning the log in between the domain & subdomain shouldn't be a problem as the cookie's domain is the same as the root domain's URL.

I've moved it on to a subdomain and it didn't make any difference (I wanted it on the subdomain anyway so at least it's not been a waste of time).

I've also tried putting the header statement in conf/settings.php - but no luck... Is there somewhere else that I could try placing the header?

Or any other ideas??

Managed to get it to work by placing the header statement directly underneath where I include wp-blog-header.php (from Wordpress).
Thanks for your help everyone!
