I've recently ran into this problem. I am using the lastest Nightly Built but I've experienced the same issue even from the last 2 builts. I'm not sure what I did but this is what the error came up when trying to access Users in Admin screen.
Parse error: parse error, unexpected ')', expecting ']' in /home/forcefor/public_html/wp/wp-admin/profile.php on line 78
Any helps are appreciated. Thank You in advance.
