Hello, I have problems too.
When I save my options, it says:
Your settings are saved.
Your settings have been reset to their defaults.
An error occurred during the action.
Then I go to the checkout backend, and it says:
Warning: Invalid argument supplied for foreach() in /home/content/74/10181074/html/recordemos/wp-content/plugins/flexible-woocommerce-checkout-field-editor/flexible-checkout-field-editor.php on line 324
What could be the problem? thanks and regards
