I just bought your plugin and when instaling it, a fatal error error occurred that stated: "Cannot redeclare iberezansky\fb3d\push_options() (previously declared in ~/wp-content/plugins/interactive-3d-flipbook-powered-physics-engine/index.php:56) in ~/wp-content/plugins/3d-flip-book/index.php on line 63"
Hi, deactivate the free version.
Hmmm... will I lost all the books I already have up with the free version? Because I need to keep them
No, do not worry about them. They are stored in the database.
It worked. Thank you very much.
