I know Pagelines is not the developer of Anything Boxes but since you operate the store I wanted to ask the following question.
Anything Boxes isn't officially updated for DMS yet but shows up in the store on one site I'm buidling: http://www.lovo.nu (http://cl.ly/image/2u0I1i3q1v1H). In another site (http://www.janpeeters.nl) that's on the same Pro version of DMS, Anything Boxes isn't visible. I'm hoping someone can shed a light on this erratic behaviour. I'd love to use Anything Boxes (that I bought) on both sites.
I read somewhere on the forum about Wordpress SEO being a problem for disappearing sections, but deactivated that didn't bring it back on my site.
