I see a similar problem and a possible fix in another thread.
bb-includes/template-functions.php open it up
find bb_get_stylesheet_uri
see if you have a backslash there.
$r = bb_get_option( ‘uri’ ) . “bb-templates/kakumei/$css_file”;
This thread will help out I think:

If not, let me know as then I am assuming you have this installed on a localhost ?

The path-to-url.php plug-in did not seem to work. Yes, I do have it installed on a localhost, and I can see where that might be a problem.
Just the same as I. Trent, I posted this yesterday or whatever..

Have a look at my post at the bottom of the thread.
Same problem and not solved by the plug-in. A few tweaks and now works great.

nanome, I had just read that post and used your tweaked code to solve the problem. Thanks so much.
While the issue technically is resolved, I think the fix creates other issues with slashes and paths. For instance, the main stylesheet displays correctly, but when I access my admin panel and then attempt to drill down into subcategories (Users, Content, Presentation, etc.), I get errors or weird redirects (gentoo.org?).
ISSUE NOW RESOLVED. I have reinstalled bbPress, this time using only a pure text editor (TextWrangler) and a different FTP client. Before I was using Dreamweaver as my interface, and you would think, after years of web work and experience with DW’s thug-like behavior with relative paths, that I would have known better.
By the way, upon reinstalling without using DW, I did not have the initial reverse-slash issue. In other words, I am not having to use the path-to-url plugin, with or without its subsequent tweak.
By the way 2: I know this would be a “duh” comment for many, but just in case it helps someone avoid the problems I had: When running bb-admin/install.php, in the field where it calls for your web site, do not enter a trailing slash. I tend to add one out of habit, and I think that was the cause of some of my earlier problems.
