Form in modular page

Hi,

due to PHP restrictions on my hosting provider side, I am using Grav 1.0.5 with Agency Skeleton 1.0.1. I have followed all instructions in the tutorial about adding a form in a modular page (http://learn.getgrav.org/advanced/forms#using-forms-in-modular-pages) but nonetheless I always get the same error: An exception has been thrown during the rendering of a template (“Template “…/forms/form.html.twig” is not defined.”) in “modular.html.twig” at line 11.

Will someone please help me get out of it?

Thanks very much.
Alessandro

Have you installed the Form plugin?
