Hello,
Thank you for the report.
Could you please try to connect to your FTP and edit the file wp-content/plugins/customer-area/src/php/core-classes/settings.class.php, line 1974, at the end of the file, you’ll see this:
/**
* @var array
*/
private $default_options;
Replace the block by that one:
/**
* @var array
*/
private $default_options;
/**
* @var array|mixed
*/
private $options;
Let me know if this fixes the issue.
Regards.
