Summary	20070: Enabling custom twig extension goes to 500 if HelloWorld extension is present
Description	When enabling in config the custom Twig extension ( 'use_custom_twig_extensions'=>true ), if the HelloWorld_Twig_Extension (that comes by default in LS package) is present, che server will crash outside the admin area. This is because it can't find the class Twig_Extension extended by HelloWorld_Twig_Extension. A solution is to change that class with LS_Twig_Extension.
Steps To Reproduce	Steps to reproduce Install LS Set 'use_custom_twig_extensions'=>true in config.php Browse a survey Expected result Everything goes as usual Actual result Server crashes with 500 internal server error

DenisChenu 2025-06-18 10:04 developer ~82895	Do you use Twig_Extension at Limesurvye ?

efornasier 2025-06-18 10:10 reporter ~82896	@DenisChenu yes, we are using Twig_Extension in different LS installations, we have some customizations that needs to be displayed in templates and easiest way is with those.

DenisChenu 2025-06-18 10:44 developer ~82898	Then maybe best to review code by someone who use it :) See my comment : https://github.com/LimeSurvey/LimeSurvey/pull/4319#pullrequestreview-2919734631
