Hi there,

Firstly thank you for your great work. I am using the plugin on this website http://tripwired.com.au/ , it used to work fine but had broken recently. Currently, I do not get email notification on new question or new answer, though I turn these on in the setting page.

Could you please kindly check the plugin function to make sure it works with the latest Anspress version.

Many thanks!
Hung
