The PDT (PHP Development Tools) plugin in Eclipse is not working correctly on Ubuntu 11.04, resulting in a 'page not found' error when attempting to run PHP files. This issue affects developers who rely on PDT for PHP development and debugging.

This frustrating error can be caused by several factors, including incorrect configuration of the Lamp server or issues with the Eclipse plugin itself. In this guide, we will walk you through the steps to resolve this issue.

💡 Why You Are Getting This Error

  • The primary cause of this error is likely due to the fact that the PDT plugin is not properly configured to use the Lamp server. The plugin may be trying to run the PHP file on a different server than the one it's actually located on, resulting in the 'page not found' error.
