When attempting to drag and drop elements to the page there is no where for the elements to go. It looks like there is not body area, just header and footer.
There is another page template system included with theme, but I was hoping to use this at the same time on certain pages.
Are you trying to say that the theme already has another page builder bundled? Chances are, it’s adding its own filter to the the_content filter that’s overriding ours. Do you mind sharing temp admin access to your site so we can take a look?
I’ve spoken to one of our developers who took a look at the theme and they informed me that the issue is that the_content isn’t in the WP loop. If you do not plan to use that themes page builder, then you could override page.php via a child theme and include the loop.
This should allows you to use Beaver Builder with that theme.
It looks like the bb-page.php template you setup is correct. If you choose that the builder should work. As an example, I also added a modified page.php to your child theme that should work without having to select a template. Let me know if you have any questions about that.
