Can;t edit user info in admincp

[محروم.كوم]

Strange problem first reported by a user who had requested a new password.


He got the password but it won't let him login - it doesn't display the usual "invalid username...." message but just displays the forum home page again (I've verified that this is what happens).

Even stranger is that when I try to modify the users profile in Admincp (clicking save without any changes is enough) it displays the forum home page in the right admincp pane?? I can edit any other users with no problem it is just this particular user. I'm stumped as to how to fix this?? __DEFINE_LIKE_SHARE__
