Signature line break

[doemasters]

Not sure where mine went on my site but any idea how to add it back. Right now a persons signature runs into their post

Thanks for any help

Update - Seems I had it the same color as my posting area, any idea on where to change the color for the signature line break

Same problem for me.
How can I change the color of post-signature separation line?

At the postbit.css template find the signature class.

.signature {
        padding-top: 1em;
        border-top: 1px solid #1B1C1B;
        margin-top: 2em;
}

Then change the color value for the border-top.
