Hi alxxcheng,
First and formost, i am sorry for the delay in response. The reason is because our plugin IG Page Builder moved to codecanyon.net and the support also there. If you have any questions, please feel free to go to
http://www.innogears.com/forums/forum/product-support/ig-pagebuilder/
However, I really happy to have an opportunity to help you here. Could you let me know your site url and let me know your fpt login account via my email tungnbs@bravebits.vn so that i can take a closer look at the problem?
Have a good day!
