Been there (for hours), done … this. It’s a sneaky line.
.footer-inside::before {
display: none;
}
Do the same for #footer-bottom if you want to remove the “powered by …” area. Maybe it removes other stuff too – I don’t know, I want my footer clean and this works for me. So, in all:
#footer-bottom, .footer-inside::before {
display: none;
}
