"Send Test Email" Mailbeez error

Mailbeez V.2.5
Module: Review Reminder - Simple
Zen Cart v1.3.9h

Hi, I have installed the above module into Mailbeez and the installation appears correct and I can access the module in my Zen Cart admin, however when I try to "Send Test Email" I get the following error:

Forbidden

You don't have permission to access /Shop/mailhive.php on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.


The 404 errordocument is not an issue, and I believe the permissions error above is actually incorrect, a red herring, as I can reach the file no problem in a browser, and using putty, and the page request returns the following: MailBeez - Mode: simulate. The file in question is set to 755.

It looks more like the module is not looking for the right path.

Any help greatly appreciated

Neil
