When I create a survey, it appears to be working correctly. I enter the survey information then go on to editing the questions. However, the surveys do not appear on the "Manage Surveys" page.
I've checked the database and the questions are stored properly but nothing is written to the surveys table. I can also use the shortcode [SURVEYS_EXTENDED 0] to display the stored questions but responses are not stored when submitted.
The plugin installed and activated OK, and all the tables appear to be present in the database. I've used the plugin successfully on a cloned WordPress installation on my private development server, but that server is Apache on Linux. The problem server is running IIS7 on Windows, with MySQL 5.x, PHP 5.x.
