Hi Guys, can you give me some assistance with adding the Facebook "Like" button to my sidebar menu.
I've ticked the box in the admin section but nothing seems to happen.
When I look on Facebook they have some script, but I am not sure where i should be adding this.
Your help would be much appreciated.
Thanks

Phil

You can paste the script into the editor using the "Insert Video or Widget" button. It's the red gear.
