Yes. That post was from two years ago, and both Graphene and WordPress have moved on in the meantime. Which version are you on? You can read the changelog [url=https://forum.graphene-theme.com/graphene-theme/changelog/]here[/url]. It doesn’t give you the details, but you can figure out quite a few things from it.
This free Support Forum relies on contributions from our support staffs and fellow Graphene themes users. While we endeavour to provide adequate and timely support, due to its voluntary nature responses are not guaranteed and may be delayed.
