Actually, here is the reason I need to solve this problem.

I’m trying to use NextGEN Gallery, in the whole it’s working fine. But when I want to add a gallery to a post or page using the “Add NextGEN Gallery” button, the tinymce pop-up menu doesn’t load properly – I get the BP 404 error page loading inside the iframe of the pop-up menu instead.

I tested this a little and found it was because the iframe URL was to a file called /window.php. I noticed that all .php files I try to load directly in the browser return the 404 error. (I tested my-domain.com/hello-world.php, and got the BP 404 page not found error!)

So, I need to stop the 404 BP message from showing and to allow the NextGEN window.php to load in the tinymce pop-up.

Does anyone know how I can achieve this?

Cheers
