I am trying to update the licence key for my MotoPress Slider installation in order to get automatic updates, but although I can see the Licence Key field on the /wp-admin/admin.php?page=motopress-slider-license page, there is no button to click on to save my changes. See http://www.gdougalldental.com.au/motopress-slider-licence.png for a screenshot of what I mean.
Probably plugin has been installed incorrectly. You can try to re-install plugin. If it is not helpful you can submit a request providing admin login data. We’ll have a closer look at your WordPress.
