We're new to CiviCRM and are just testing in a test environment. On a couple of occasions logging in, this warning message has appeared:

Warning: ini_restore() has been disabled for security reasons in CRM_Utils_VersionCheck->pingBack() (line 301 of ... VersionCheck.php)

Could someone please explain what is happening in pingBack() (see below)?

What is "ini_restore('default_socket_timeout');" supposed to restore?

Would there be problems if we went into production with ini_restore() still disabled? (We can enable it in php.ini, but I'm curious)

Thanks, Arthur
