I have added a hero slider in my WordPress site using the slider revolution. However I couldn’t add/edit button link using the “Actions” window. The Actions popup window seems freeze within Slider Revolution plugin. Can someone explains me why is this? Is this because I need to buy the premium version of Slider Revolution to give a button link? I have attached a screen shot of this. Please advise. Thanks.

I uploaded new slide images. But its not showing the full image. Tried to resize image. Nothing working. Top image is hidden by the menu and sides of the images are not showing. Its showing like zoomed out image, showing only center and right
