Re: Friends link, plus
1.. make sure the template file for your member theme contains /friends/index.php and everything is kosher there.. and then make sure that you don’t have another page/post named friends, and you don’t have a url rewrite rule for friends in your. htaccess file.
2. the avatar upload is most likely due to misconfig of the GD Library.

3. default for the home page? did you change the theme? can you put up a link?
