Media Grid limits photos to 3 pictures
I am trying to add photos to my media grids and after adding 3 pictures the media grid will not allow me to add more. It will erase what was added and then start adding new photos. I want to scroll through the pictures 1-20 etc. At the moment I have had to add several media grids on one page which will only allow me to scroll through 1-4, click on next section and click 1-4 again. What is going wrong?
