iThemes Security and PHP 7

Same here: The content of the Dashboard page (/wp-admin/admin.php?page=itsec) breaks after

Database Information
MySQL Database Version: 5.6.25-73.0-log
MySQL Client Version:
Fatal error: Uncaught Error: Call to undefined function mysql_get_client_info() in /var/***/wp-content/plugins/better-wp-security/core/content/system.php:70 Stack trace: #0 /var/***/wp-content/plugins/better-wp-security/core/class-itsec-dashboard-admin.php(119): require_once() #1 /var/***/wp-admin/includes/template.php(1037): ITSEC_Dashboard_Admin->metabox_normal_system_info(NULL, Array) #2 /var/***/wp-content/plugins/better-wp-security/core/class-itsec-core.php(1578): do_meta_boxes(Object(WP_Screen), ‘advanced’, NULL) #3 /var/***/wp-includes/plugin.php(525): ITSEC_Core->render_page(”) #4 /var/***/wp-admin/admin.php(236): do_action(‘toplevel_page_i…’) #5 {main} thrown in /var/***/wp-content/plugins/better-wp-security/core/content/system.php on line 70

I found out that mysql_get_client_info() was removed in PHP 7.

Method I:
Contact hosting service provider where MySQL version is higher than 5.5.40. Ask them to load atleast MySQL v5.5.40.

(or)

Method II: Temporary solution
Edit line no.70 in system.php file at
wp-content>>plugins>>better-wp-security>>core>>content>>system.php

After finding the above system.php file edit line no.70 like this:

mysql_get_client_info() to mysqli_get_client_info()

Note for method II:
Whenever a plugin updated, the above process need to be repeated again

Seems to be issue resolved after the latest version v5.2.1
