i mean this part of your explanation, in the 3rd party cookies configuration. I have php version 7.0.1
"If your server runs PHP 5.3 or greater and PHP Reflection is included with your PHP installation, then you have some options for preventing 3rd party cookies. Those on GoDaddy Shared Hosting - add "AddHandler x-httpd-php5-3 .php" to your .htaccess file and you'll be switched to PHP 5.3 with the proper Reflection classes.
The plugin configuration will inform you if your server is not capable of handling this configuration. Within the "Advanced Options" slider, look for this message "Your system lacks the PHP Reflection classes; as a result, this feature is not available on your server."
If you don't see that message, then you'll be presented with an option to select a "View Level". Stop here, you have some configuration to do within the "User Manager"."
