My apologies, this is a known error, fix coming soon.
Problem: Your host is running an old version of PHP. Look at your phpinfo() and you will see php <= 5.2
For now you can upgrade your php by contacting your host, or install the old version by browsing the ww.wp.xz.cn website.
Again, my apologies for the inconvenience.
I have just finished the restructuring. Please try the newest version, 2.0.2 and let me know how it goes. It has more options and updated javascript with partial mobile support.
Activated fine!!! Awesome.
Messing around now and things are running smooth. Great plugin!
Thanks for the quick update.
