Important Notice
Not sure where the Slider’s shortcode was added to your web page?
It’s possible a Slider has been manually added into your theme’s PHP files. Often when this is the case your theme will have a special option for choosing a Slider. Refer to your theme’s instructions to learn if your theme is setup this way.
