As I said in my last post: ” to first make sure you created the slider properly, try inserting in in the content of a page you created, using the Add [Show_slider] button above the content editor and selecting the slider you created by its name.”
So you go to your page editing page
Above the content editor there is a button Add [Show_slider], you click on that.
In the popup that opens there will be a drop down list to choose a slider, if you only created one, its name will be the only one in the list so select that, then click the Add Button.
Update the page and preview.
