Warning: Invalid argument supplied for foreach() + Warning: Cannot modify header

[mwhithamParticipant]

Every time I change the role and click “save data” in my member directory I’m getting the following error message on a blank screen. The change I made does stick, but I need to know if something is messed up in our installation.

Warning: Invalid argument supplied for foreach() in /home/customer/www/xxx.com/public_html/wp-content/plugins/swpm-form-builder/classes/class.swpm-fb-formmeta.php on line 95

Warning: Cannot modify header information - headers already sent by (output started at /home/customer/www/xxx.com/public_html/wp-content/plugins/swpm-form-builder/classes/class.swpm-fb-formmeta.php:95) in /home/customer/www/xxx.com/public_html/wp-includes/pluggable.php on line 1329

The lines surrounding line 95 were these:

    public function load($form_id, $load_fields = true) {
        global $wpdb;
        $query = $wpdb->prepare("SELECT
            form_id AS id,
            form_key AS _key,
            form_title AS title,
            form_type AS type,
            form_membership_level AS for_level,
            form_success_type AS success_type,
            form_success_message AS success_message,
            form_notification_setting AS notification_setting,
            form_notification_email_name AS notification_email_name,
            form_notification_subject AS notification_subject,
            form_notification_message AS notification_message,
            form_label_alignment AS label_alignment
        FROM $this->table WHERE form_id=%d", $form_id);
        $data = $wpdb->get_row($query);
        foreach ($data as $key => $value) {
            if ($key == '_key') {
                $this->key = $value;
                continue;
            }
            $this->$key = $value;
        }

Line 95 is this one: foreach ($data as $key => $value) {

Thank-you so much for your time to take a look at this issue!

Hi, is the above your own custom PHP code?

Thank you

This is the code that should have come with the plugin – it’s in the plugin folder. I didn’t make any changes.

Also what PHP version is running in your server?

Thank you
