i've added a few hacks to my board and additions to my store.... and unfortunately i have only just now been told that..... when someone tries to register at my boards they are given this message:

Please make sure that you have completed all the required fields. These include username, password and email. Press the back button, correct the error and try again.


i even tried to register and got that message, even though every field is filled out completely.... how can i fix this?...thank you in advance
