The WP MortgageCalculator plugin for WordPress was designed to provide a straightforward mortgage calculation tool for websites. However, it has been closed since November 3, 2011, and is no longer available for download. The specific reason for its closure was not disclosed, and the plugin has not been updated in over a decade, rendering it incompatible with modern WordPress versions. Users seeking similar functionality are advised to consider alternative, actively maintained mortgage calculator plugins to ensure compatibility and security.
