We have release a quick update for Roster Slider to fix the responsive design issue on small screens. With Roster 1.6.1, you can see the auto-adjusting slider images (in case of pure image slider) on different screen sizes. You can update to the Roster 1.6.1 by downloading the same from “My Downloads” page and upload the unzipped folder to wp-content/plugins folder on hosting server. Deactivate and re-activate the plugin.
Feel free to let us know your thoughts about this update using the contact form.
