CiviCRM Smarty3 errors...
When updating to ESR 5.69.x, we are running into errors with Smarty3 when updating the smarty path in civicrm.settings.php:
define('CIVICRM_SMARTY3_AUTOLOAD_PATH', '/var/www/example.com/sites/all/modules/civicrm/packages/smarty3/vendor/autoload.php');
$Fatal Error Details = array:3 [ "message" => "undefined extension class 'Smarty_Internal_Runtime_Get_Plugin_Filepath'" "code" => null "exception" => SmartyException {#8284 #message: "undefined extension class 'Smarty_Internal_Runtime_Get_Plugin_Filepath'" ...
We are still trying to diagnose why this is happening, but we have upgraded some clients with no issues, and other clients with varying degrees of issues. Has anyone else encountered this issue when upgrading to 5.69.x?
