If you have a Professional or Developer license, the recent PageLines 2.1.4 update changed how the PageLines Leaf logo/watermark is displayed.
Prior to the update, the Leaf logo was automatically removed for those who had a Developer License. With this update, Both PageLines Professional license holders & Developer license holders have the option to remove the leaf from the bottom of their site.
In addition you can now upload your own the logo & link it to wherever you want.
From the WordPress Administrational Panel:
There you can make your changes.
