View More Link Issue

Hi,
this plugin appears to be great and I was about to purchase it for my client so I could customize colors and such, when I realized that when I would enter the address for the view more link, it would cut off part of the address when I would save it. It’s a relatively long address so I’m not sure if that is the problem? The links worked fine on the wp basic galleries. I would really like to hear back soon so that I can fix the problem and purchase this plugin or move on since all of my customers’ links are currently not directing to the appropriate place.
Thank you for your time,
Pete
