Hey, thanks for your feedback.
Yes, I did include it in a demo.html. Not in an standard template of wordpress.

Therefore, the code of the plugin works. It must be include in the right positions. And for this I would like to have support from the theme developers – and that is your company. The developer of the plugin says nearly the same as you: My Plugin works, aks the template developers.
And as a software developer I understand the points of you both. But because the template code is generated with a little bit of “magic” I think now more help should be given by you.

In the plugin, there are only 4 Lines of code. It is really easy. But I have to understand where and how I have to include it into the Enfold Template. It is not so easy to open the php-page and add some code to the header and some to the body. There ist the template configuration, the function.php, the page creator and the blocks itself.

From my side difficult to understand – but it works and thats great.

Now, I need some help from you to include these 4 lines of code into your template.
Perhaps we can do this on a Zoom-Call and discuss it directly.
