Yes, Dancer2 Template Toolkit is installed. Curiosly when I swithc back to simple template in config.yml the basic dancer app works. So I do not understand why it would not if TToolkit is installed. However, when I switch to TToolkit I continue to get this in my browser:

Again, this is just the basic Dancer2 app created with: $: Dancer2 -a MyApp.

Here is my config.yml file.

# This is the main configuration file of your Dancer2 app
# env-related settings should go to environments/$env.yml
# all the settings in this file will be loaded at Dancer's startup.

# Your application's name
appname: "MyApp"

# The default layout to use for your application (located in
# views/layouts/main.tt)
layout: "main"

# when the charset is set to UTF-8 Dancer2 will handle for you
# all the magic of encoding and decoding. You should not care
# about unicode within your app when this setting is set (recommended).
charset: "UTF-8"

# template engine
# simple: default and very basic template engine
# template_toolkit: TT

#template: "simple"

template: "template_toolkit"
# engines:
#   template:
#     template_toolkit:
#       start_tag: '<%'
#       end_tag:   '%>'

Thanks for any help.
