To fix this problem on your board you'll need to go into Custom Templates and go to the Thread template and press the "Reset to original" button.


OR

If you've customized the thread template and don't want to reset it, you can also delete the following text from the thread template:
<input type="hidden" name="fieldusername" value="{iftrue_qreply.usr}"><input type="hidden" name="fieldpassword" value="{iftrue_qreply.pwd}">
It's located a few lines below <!-- BEGIN iftrue_qreply -->
