Where do I got to edit the line above sigs. I have a black theme, so you can't see it.
Thanks.
Admin CP > Themes > edit the MyBB Master Style > go down to "Additional CSS" at the bottom > find the hr entity and change it to something like:
hr {
background-color: #FFFFFF;
color: #FFFFFF;
height: 1px;
border: 0px;
}
