为什么不解释Twig标签？

I am currently setting the standards a PHP project that was coded framework and without the former (JS / SQL / PHP in views). So I refactored a good big portion and I am putting in place the framework and Silex Twig template engine for views. My problem is that Twig tags are not executed (they are quoted): Source code HTML

What you see: Error Twig

Here's the code of my Twig page in question, there must have syntax errors I think:

<!DOCTYPE html>
<html>
<div class="navbar-collapse collapse templatemo-sidebar"></br>
    <ul class="templatemo-sidebar-menu" id="listMenu">

                <input type="text" class="form-control" id="templatemo_search_box" placeholder="Rechercher..." onkeyup="refreshSearch()">
                <span class="btn btn-default" onclick="searchItem(templatemo_search_box.value)"><i class="fa fa-search"></i></span>

Please, add php code, where you define Twig; It seems that you set wrong path for inlcudes;

Check where you define template folder. And set path in template relative to you template path.

$loader = new \Twig_Loader_Filesystem(__DIR__.'/v2/Templates');
