Solution is simple. If you are using PHP 7 or higher 'mcrypt_create_iv' is no longer supported in PHP 7. How to fix it? Look at below example.

My old code:

if (function_exists('mcrypt_create_iv')) $randomData = mcrypt_create_iv(20, MCRYPT_DEV_URANDOM);

and I need to make some changes like this:

if (function_exists('random_bytes')) $randomData = random_bytes(20);
