I'm using Silverstripe v.2.4.1 and I need to insatll a gallery. I follow this guide and I download and install this 3 module but my gallery doesnn't work. I can build module but when I try to create a new gallery page and I try to save i have an error. I need help in gallery with v.2.4.1 . Is it possible install gallery in SS v.2.4.1? Is there an other version of gallery?
