Technote Details :: Issue when creating a database connection: HTTP Error Code 405 Error
Issue
When creating a new ADODB database connection on the PHP_ADODB server model, I get an error message saying HTTP Error Code 405 Error.
Reason
This happens because the web sever that runs on the testing server you have specified in the site configuration does not support PHP as a scripting language.
Solution
In order to solve this, you must install PHP on the web server.
You can get PHP from www.php.net , and follow the instructions provided to install it correctly for your server's operating system and web server.
