That plugin requires the installation of a special template functions which allow the Forum Admin to decide where to display the share buttons. These display template functions are installed into your Simple:Press Forum Theme files or can be used in other WordPress pages or widgets.

Take a look at the codex page and it will give you some examples.

We recommend you create a custom theme first. Information on installing custom themes are located on our Creating a Theme page.

ok.. so its not a plug and play..

i tried to read that create your own custom theme.. WAAAY above my pay grade.. thats unfortuante..

oh well onward and upward.

Don’t give up so easily. It really is very simple. All you really need is a decent plain text editor, access to your server and a dose of common sense…

@Daniel… plug and play?  we chose not to make it come out to one specific area because that would be very limiting and discouraging to a lot of users…  not everyone wants it in the same location…  Brandon and I, for example, display them in different locations…  use of a template tag offers the most flexibility for users… but yes, does require you to add the template tag where you want it…
