I have uploaded a new version of the "KC s2M Pro-rates" plugin. The main changes are:
- The "By Sum" mode now works.
- Multi-option shortcodes are supported; remember to select "Shortcode Text".
- Custom capabilities, or ccaps, can be changed. Both the old and new ccap sets must have corresponding rows in the price plan table.
The release also includes bug fixes and improved admin input controls. All users are encouraged to update the plugin.
