How to remove an error when clicking on a user link in the Bitrix CRM control panel?

Question

1C-Bitrix

We are trying to edit user data in the control panel -Settings-List of users and we get the following error as in the screenshot. For a new user, the card opens normally. How to fix?

Answer 1

Must be added to settings.php

'crypto' => 
  array (
    'value' => 
    array (
      'crypto_key' => 'КЛЮЧ',
    ),
    'readonly' => true,
  ),

instead of KEY to insert on the recommendation of Bitrix,
we advise you to install a 32-character string from a-z0-9

Answer 2

yum install php-mcrypt
