Hi Cipa, I have installed the Plugin online and it’s working, so it’s only when I try to use it offline that I get the error.
I don’t know why, but thanks for your help!
This should be the right one: "http://rtfm.modx.com/display/revolution20/Field+Default", for example if I change "name:category" with "name:template", but it seems that I cannot target a specific category and sub category to use a specific template.
