I am using WPSHOW 1.1.3 and GP (current full release)
I have set up staging site as I didn’t want duplicate content being shown
And in response to you question, Yes. Three WPSHOWPOST item with a side widget, which is shown on all posts
The first will be 2 pinned post, ie i have stated the post ID in the setup.
The other two, I am have added those same post IDs to the exclude section – but they are still being displayed.
I have sent the URL via contact – if you want access to WP-admin I can set you up an account.
