You can tweak FlexForm to an extent in your Localsettings.php

$wgFlexFormConfig['secure'] = true; //( default is true ). Will render form that make no sense when inspected in the browser

$wgFlexFormConfig['sec_key'] = ""; // A salt key for encryption. Used together with "secure" option. Must be set when using multiple instances of a wiki

$wgFlexFormConfig['auto_save_interval'] = 30000; // defaults to 3 minutes.

$wgFlexFormConfig['auto_save_after_change'] = 3000; // defaults to 3 seconds after last change

$wgFlexFormConfig['auto_save_btn_on'] = 'Autosave on'; // text on the autosave button to toggle on

$wgFlexFormConfig['auto_save_btn_off'] = 'Autosave off'; // text on the autosave button to toggle off

$wgFlexFormConfig['FlexFormDefaultTheme'] = "plain"; // Currently the only form

$wgFlexFormConfig['rc_site_key'] = ""; // reCaptcha site key

$wgFlexFormConfig['rc_secret_key'] = ""; // reCaptcha secret key

$wgFlexFormConfig['file_temp_path'] = ""; // Where to store images temporarily that need to be format converted

Finally

Add the following line at the end of your LocalSettings.php to enable the extension :

wfLoadExtension( 'FlexForm' );
