I’ve had success using BB with some other themes, but this weekend I was working on a new site & ran into trouble. I can open my page with Beaver Builder, but I can’t seem to add and rows or elements. I also tried just using a template, and that wouldn’t show up either.
I did some testing and it looks like the issue is with the Genesis Connect for WooCommerce plugin. When I disable that, the pages are editable with Beaver Builder. I tried to recreate this on my site with your theme and that plugin, but everything is working fine.
I did notice that even the default WordPress editor isn’t working for pages on your site, so I don’t believe that the issue is with Beaver Builder. You can see that happening here… http://dahlhousedesigns.net/test-2/
That page should have content from the WordPress editor, but instead it contains an empty products UL tag…
<ul class="products"></ul>
That leads me to believe that something is causing WordPress to think that your pages are product archive pages instead of regular pages.
I would suggest posting in the support forums for the Genesis Connect for WooCommerce plugin to see if they can get this resolved for you. I tried to figure out what it might be but didn’t have any luck.
