New Password length minimum: 7. Non-alphanumeric characters required: 1.

 IÃ?´m testing my ChangePassword page so that i can change my username and password in my website but i get this message:
New Password length minimum: 7. Non-alphanumeric characters required: 1.
 
I created a user to manage the contents of the website and my pass was admin123$ which was filling the requirement above but then i�´ve changed the password because i was also testing my RecoverPassword page. Since i need my older pass to give to my teacher so that she can test my website i tried to change it again in my ChangePass site but this message shows up.
Am i mising something?
