The code is correct and shouldn't cause any problems. Here are a few things you can try:

• Make sure you've installed the extension correctly
• Check that the spelling in file names and class name is correct. Linux is case sensitive.
• Check your extension folder protected/extensions and make sure that the directory EStrongPassword (case sensitive) exists
• Make sure the path is correct (ext in your script refers to protected/extensions path)

The file should be at:

protected/extensions/EStrongPassword/EStrongPassword.php

Hope this helps!
