Topic: Html Shortcodes Require PHP
For HTML projects, Shortcodes require PHP. Be sure to build your pages with a .php extension.
If your .html pages are already indexed, you won't be forced to rename them. Mpc now includes a utility for configuring your webserver to scan .html pages for PHP code.
Right-click the Source Files list box. Select "Enable PHP in Html". Test your page file extension and if need be, enable it for PHP. (Apache server only).
