Cannot save Settings (AJAX issue)

Please me know if you have any complexity with plugin itself and have any question. If you want to change avatar, you can add one here http://en.gravatar.com/

in that case, you need to change it directly from template file in tpls dir.

Please give me temporary wp-admin login info in a private reply to check.

Login info is not working.
