Today was released version 1.3. PHP version was downgraded to 5.6 so you will not see problems like:
Parse error: syntax error, unexpected ’?’ in /var/www/vhosts/grawebtasarim.com/httpdocs/wp-content/plugins/3d-flip-book/inc/post-pages.php on line 48
It has some new features see the description for details.
Sorry for the inconvenience. Thanks for understanding.
