Plugin "Table of content creator" issue

Hello,

I'm using plugin Table of Content Creator http://wordpress.org/plugins/table-of-contents-creator/ about several years at my site http://www.technologymag.net/vi/sitemap/

The plugin does not supported anymore so when i tried to using for my new site: http://www.nhadep.net/vi/sitemap, the plugin does not work.

This is the page i have created to show table of content: .It's just display blank page.

Please help me take a look.

Thank you,
Tuan.
