globale theme changing

Hey @makmerghen,

If the theme you’re using offers action hooks within the post template, we can use those to hook a BB template via our shortcode. You can check the KB articles for more info.

If the theme doesn’t offer any, or the hooks aren’t to your liking, you can override the theme’s post template via a child theme. You can check the codex below for more info.

If you haven’t yet, I’d suggest checking out our Beaver Themer plugin. It’s an add-on to the page builder which allows you to create your own post/archive/search/404 template using our page builder. And if the theme is supported, you can create your own header and footer as well! You can check the page below for more info. 🙂

Hope this helps, and let us know if we can assist further!
