Fatal error: Uncaught exception ‘Twig_Error_Runtime’ with message ‘The “Twig_Extension_Core” extension is not enabled.’ in C:\xampp\htdocs\shopg\wp-content\plugins\shopmagic-for-woocommerce\vendor\twig\twig\lib\Twig\Environment.php:793 Stack trace: #0 C:\xampp\htdocs\shopg\wp-content\plugins\timber-library\lib\Twig.php(223): Twig_Environment->getExtension(‘Twig_Extension_…’) #1 [internal function]: Timber\Twig->add_timber_escapers(Object(Twig_Environment)) #2 C:\xampp\htdocs\shopg\wp-includes\class-wp-hook.php(298): call_user_func_array(Array, Array) #3 C:\xampp\htdocs\shopg\wp-includes\plugin.php(203): WP_Hook->apply_filters(Object(Twig_Environment), Array) #4 C:\xampp\htdocs\shopg\wp-content\plugins\timber-library\lib\Loader.php(166): apply_filters(‘timber/twig/esc…’, Object(Twig_Environment)) #5 C:\xampp\htdocs\shopg\wp-content\plugins\timber-library\lib\Loader.php(66): Timber\Loader->get_twig() #6 C:\xampp\htdocs\shopg\wp-content\plugins\timber-library\lib\Timber.php(286): Timber\Loader->render(‘partials/sideba… in C:\xampp\htdocs\shopg\wp-content\plugins\shopmagic-for-woocommerce\vendor\twig\twig\lib\Twig\Environment.php on line 793
