Hatch is a great theme. Thank you for providing a freely available version of it.
However, we seem to be having conflicts with it and a few plugins. I'm not sure where the fault lies in either instance, but thought I'd post here so the developer(s) can look into it.
The other problem is with the Groups plugin: http://wordpress.org/extend/plugins/groups/. With it, there's an error that appears at the top of the Theme's Settings page in the Admin, and no where else (at least that I've seen thus far). I've posted all the details in the Groups support forum, but thought you might like to have a look at this as well: http://wordpress.org/support/topic/error-when-using-hatch-theme
