My second attempt here to get some help on this. I just bought the Unreal flip book file for $35 & ($2 handling?), and uploaded it as a plugin to my wordpress site. When i tried to activate it, it said: Fatal error: Cannot redeclare iberezanskyfb3dget_dump() (previously declared in /home/b5ev8zhgq6ip/public_html/wp-content/plugins/unreal-flipbook-addon-for-visual-composer/index.php:15) in /home/b5ev8zhgq6ip/public_html/wp-content/plugins/unreal-flip-book/index.php on line 19 Do i need to deactivate the light version first which i have been using?
