Login / logout problem

[Anhinga]

I've just bridged my Coppermine gallery with an SMF forum following the steps described at http://coppermine-gallery.net/demo/cpg14x/docs/index.htm#integrating_steps_start , but I've run into a problem:  when I try to log in or out using the button on the Coppermine page, instead of redirecting me to the SMF forum it doubles the URL.  So for example, the most recent time I tried to log out from the Coppermine page it took me to http://snakebird.net/polaris/www.snakebird.net/gallery , which gave me a 404 error.

The URL of my forum and Coppermine gallery are www.snakebird.net/polaris and www.snakebird.net/gallery, respectively.  I've created a test account called "Test"; the password is "coppermine".

Here's the information from the bridge manager:
Forum URL:  http://snakebird.net/polaris
Relative path to your BBS's config file:  ../polaris/ 
Use post-based groups?:  0

I've also tried this with the forum URL as http://www.snakebird.net/polaris, but it gives me the same result.  What do I need to do in order to fix this?

Add the http:// to your site url in config.

Thanks, it looks like that's fixed it.
