getSelections not working? in modx?

Question

MODX

I started to study modx, got to the point of displaying just blocks of news, created a collection, scored news, trying to display it in this way (from the plugin's off-line documentation)

But instead of items, the error "getResources not found" is displayed Tell me
what could be the error, maybe someone has met this

Answer 1

To work, you need the getResources snippet, install it
