Hey, this extension has been abandoned and is no longer supported by me (as stated in the description) so you'd have to create a fork and modify the source code if you want to have it work on your server.

I see you're using the "Actions" extension. You could also create plugins using the code from my extension; that'd be easier since you don't have to bother with any C++ code.

Thanks for replying, understood.
