Hi, I'm exploring a mechanism in which the settings page(s) are used to write global CSS-styles. I need to clear cache plugin after an update to the settings has been performed.

I can't seem to find a way to easily determine if an update has been performed. I can hook the callback with a priority 20 or higher, which makes it run after the save, but don't want to run it all the time. I know I can hook into mb_settings_page_load to do some actions after save, but the $args don't tell me there has been an update or initial save action. Maybe I'm missing something, can you point me in the right direction?

Hi,

I think you need to track the 'initial save' or 'update' with a custom option, like this:
```
add_action( 'mb_settings_page_load', function() {
    $is_updated = get_option( 'your_custom_option' );
    if ( ! $is_updated ) {
        do_your_work();
        update_option( 'your_custom_option', 1 );
    }
}, 20 );
```
