I have installed your WPBakery plugin and set it up so far. Embedding on the side works. Problem: When I am logged in at wordpress, the pdf and the function are displayed - scrolling and function works without any problems. However, the plug-in does not work as a visitor to the website who is not logged in. Where's the problem?
Probably you have a security plugin/theme settings that hide custom post type 3d-flip-book from unauthorized users. Also clear the optimization plugins cache if you have them.
Hello, Thanks for your answer! The problem is fixed. It has to du with an optimization plugin on my website - i deactivate this plugin. Thanks for your support.
