 Hi, I was getting a lots of errors while doing disable the cache from opencart admin by clicking on this button. like this "Notice: Trying to access array offset on value of type null in vendor\scss.inc.php on line 1753" to fix this error.

 Hi, I was getting an error while including twig file into twig file by this code {% include 'extension/import/productimport.twig' %} since this code is working in my Opencart version 3.0.3.3 but not in Opencart version 3.0.3.6 so I fixed it by following way.
