Magento 1.9 on PHP 7.2 - phpseclib failed to open stream

[dandrikop]

I have installed the latest Magento version 1.9.4.5 on PHP 7.2.33. At the file /var/log/system.log, I frequently see the below lines:

DEBUG (7): include(Phpseclib\Crypt\Base.php): failed to open stream: No such file or directory /lib/Varien/Autoload.php
DEBUG (7): include(Phpseclib\Crypt\Base.php): failed to open stream: No such file or directory /lib/Varien/Autoload.php

I have checked the below files under the Magento root directory and they are all exist:

/lib/phpseclib/Crypt/Base.php
/lib/phpseclib/Crypt/Blowfish.php
/lib/phpseclib/Crypt/Random.php 

Is this problem related with PHP 7.2?

Hello @dandrikop,

Check if the included files require these files (/lib/Varien/*) so you are facing this issue.
