Sounds like a bug. Try the following. Edit wikiform.php and in
function EntryForm look near the top for

        if (PageExists($pagename)) {
            $editing = true;
            $fve = FormValues($pagename,$f);

Change this to

        if (PageExists($pagename)) {
            $editing = true;
            $fve = FormValues($pagename,$f,'edit');

What this should do is force a password prompt before it loads 
the data into the editing form.

I haven't tried this, so let me know what happens.

Can you also tell me what line 444 is in your version? I think it's
in the function FormData, but this contains several implode calls.

You could also try adding "echo $f[$i]['element'];" immediately
above line 444, to see what it thinks it's trying to implode. That
may give us a clue.

Do I understand that if you *are* logged in, it works correctly?
