I just checked the site and this is what I’m seeing(see screenshot). I also tried the code on my local and I get the same thing. http://imgur.com/6hFhm1R
Upon viewing the page source for the quickpictours site, I’m going to speculate that the issue is a result of a conflict between BB and Themify Builder and all the add-ons. Generally, it’s never a good idea to have more than one “page builder” active at the same time.
A good way to troubleshoot the matter is to temporarily disable the other plugins and see if BB now displays as desired.
This is caused by the SSL setup on your site. The iframe is blocked since it is being loaded insecurely. Try changing the source from http to https and see if it works. If it doesn’t, try contacting the guys who provide the code and see if there is a way to load it into a secured site. I could also be wrong and you may try Lyle’s suggestion above.
Actually I’ve used BB & Themify in tandem on a few other sites and have never had any issues. However, I went ahead and deactivated Themify completely on the site. I also went through one-by-one with each of the plugins and deactivated them. Right now the only thing that is active is Beaver Builder, CSS Hero, Code Snippets, WP Analytics, and WooCommerce. Still it’s not working. I’ve embedded the code 3 different ways: HTML, Video, and Text Editor modules. Still it won’t show up. Any other suggestions?
