User profile data missing and edit link not working.

Hello,

Thank you for the very great support I've received on previous questions. Here are a few more I have:

1) The user profile data seems to be lost on the qa user profile page. For example, the gravatar changes to mystery man, the name = blank, the member for reads "member for 46 years" [sic], and the website is blank (though the wp_user data for the user I'm looking at is visible on my dashboard)

2) Under each question and answer post written by the author, there is a "link|edit|delete|report" menu. "delete" and "report" work fine, but "edit" goes to a page that is "Not Found" for all questions and answers I have tried. The "link" link seems to do nothing.
