I'm using metatags-quick and the following token modules:
- Entity tokens (7.x-1.0-rc1)
- Token (7.x-1.0-beta7)
- Token Filter (7.x-1.x-dev)
In the MetaTags Quick config, we've set description to be automatically generated from the Body summary field. The body summary default is set to:
[site:name] - blah blah blah - [node:field_artist_name] - [node:title]
The site name token is properly rendered in the meta description, but the other two are not.
