Removing chatbox

Hello,

so I'd like to install FMChat on my forum..
But I already have a pop up chatbox from earlier, which create an overlapping toggle at the corner of my page.

Left: FMChat / Right: OldChat

The problem is, I forgot where did I put the codes for the old one.
I'd like to remove the old chatbox, and start using FMChat.

Thank you.


Edit:
nvm I found it under overall_footer_begin
