Thanks for the PM and thanks for the theme fix too. I wil apply them later and feedback if there are any issues
Update: I've just checked my template file and I already have this fix in place and the file was last updated in May last year.
<input type="hidden" name="hash_passwrd" value="" />
<input type="hidden" name="', $context['session_var'], '" value="', $context['session_id'], '" />
