I'm not sure, if this problem relates more to WordPress MU or BuddyPress. I've set up a website using them both, but I can't get the avatars to display. When the user uploads an avatar image, there is no error message and the image gets saved in /wp-content/blogs.dir/. However the image isn't displaying at any point, and I've figured out, that the file name for the image, that is being retrieved on the website, is different from the file name in blogs.dir. The file names in blogs.dir are the original names, whilst the file names on the website have been rewritten. For some reason the name rewriting process isn't happening for the images in blogs.dir folder. Does anybody know why that could be, and how it could be fixed?
