Needs more arrow.
I used to be a forum owner like you until I took an arrow to the knee.
There's no way that I know of to disable the output from those other mods, though if you find their postbit templates you can copy / paste it into a new PBTabs View, the HTML and everything should still work. If it doesn't, then there's sadly no way
This is not a bug in PBTabs, though.
