WordPress Landing Pages

Hello,

I have downloaded and installed WordPress Landing Pages Plugin on my site, the plug in works great but I just have one small issues, I have a subscriber website and I want to give access to my subscribers to be able to make landing pages using this plug in, but when I try to create a landing page as a subscriber I get the message that “I do not have sufficient permissions to access this page”. Is this is a default restriction in the plug in or is it something I am doing wrong. If it is a default restriction is there any way to remove the restriction and to provide access to my subscribers to create landing pages using “WordPress Landing Pages”??

Thanks,
