[Plugin: Sliding Panel] Can see tab, but can't get it to open.

I’ve seen this has come up a couple of times, but no one has posted exactly how they did it.

I have installed the sliding panel plugin (view it here https://dshop.dropdeadgorgeousdaily.com) and you can see the tab, but the tab doesn’t open.

Apparently I need to move some code? Not sure what to move and to where, newb instructions would be ace.

Thanks ??
