ttyl123 on "[Plugin: iThemes Security (formerly Better WP Security)] The page cannot be displayed because an internal server error has occurred error"

Hi, I just installed the latest version of Better WP Security on my new site running on Azure. After the installation, I would get the following message when I try to access any of the Better WP Security options:

The page cannot be displayed because an internal server error has occurred.

Please help!
