Uncaught Error: Call to a member function _callExternalMethod() on null in .../smarty_internal_data.php:283

[tf]

Hey guys,

I try to upgrade the environment for my IdoIT Open 1.11 from PHP 5.6 to 7.1. (Apache 2.4.6, php-fpm 7.1.20)
I noticed this error:

[02-Aug-2018 13:07:42 Europe/Berlin] PHP Fatal error:  Uncaught Error: Call to a member function _callExternalMethod() on null in /var/www/html/idoit/vendor/smarty/smarty/libs/sysplugins/smarty_internal_data.php:283

Can you give me a hint what might caused this? Do I need to change idoit configuration for PHP 7.1?

Thanks in advance,

In /var/www/html/idoit/src/classes/libraries/isys_library_smarty.class.php in public function __construct($p_options = []) move the line parent::__construct($p_options); to the beginning of the constructor.

@franknagel Thanks, this fixed the issue.
