I am using open cart version 3. And I got the following message: Twig_Error_Loader in open cart after replacing theme files.

Code: Select all

Fatal error: Uncaught exception 'Twig_Error_Loader' with message 'Unable to 
find template "common/column_left.twig" (looked into:

it looks that the problem resides in catalog/controller/event/theme.php

the Code assigns a path only when $theme:info isn't set.

Code: Select all

 if ($theme_info) {
        $template = html_entity_decode($theme_info['code'], ENT_QUOTES, 'UTF-8');
    }elseif (is_file(DIR_TEMPLATE . $theme . '/template/' . $route . '.twig')) {
        $this->config->set('template_directory', $theme . '/template/');
    } elseif (is_file(DIR_TEMPLATE . 'default/template/' . $route . '.twig')) {
        $this->config->set('template_directory', 'default/template/');
    }

I modified the code to this. Now a path is asigned and the whole thing works. You still have to reload the cache to see modification.

Code: Select all

if ($theme_info) {
        $template = html_entity_decode($theme_info['code'], ENT_QUOTES, 'UTF-8');
    } 
    if (is_file(DIR_TEMPLATE . $theme . '/template/' . $route . '.twig')) {
        $this->config->set('template_directory', $theme . '/template/');
    } elseif (is_file(DIR_TEMPLATE . 'default/template/' . $route . '.twig')) {
        $this->config->set('template_directory', 'default/template/');
    }
