Template path application/meta/variable

application/meta/variable[name] no longer returns the value of the variable.

To get the variable value, use the new path: application/meta/variable[name]/value.

If the new path is not used, you will get an error such as this:
Rendering error...
Template snippet: _default, style '_default', line 107
