Fleur comes with a pre-designed Bloom Optin form.
To import the Bloom form you must have Bloom installed which is not included with this child theme.
With Bloom installed, in the WordPress admin panel navigate to Bloom>Import & Export, select ‘Choose File’ under ‘Import Bloom Settings’ and select the file called fleur-bloom-settings.json from your computer, then click on import
You should get a message saying the import was successful, next click on Bloom>Optin Forms and you will see the form in the Inactive Optins section. You need to make sure you have added your account details for your email service provider to the Bloom settings and then selected a list for the form.
Next click on the tick next to the form to activate it and it will move up into the Active Optins section.
The form should now be active on your site. If you still see a shortcode displayed then check the ID of your Bloom form and change it in the Bloom Global module in the library and also in the layouts that display it.
