Symfony 2 debug toolbar not showing

The Symfony debug toolbar doesn't show up.

I am running the site on app_dev.php environment. The config_dev.yml file contains the following lines.

web_profiler:
 toolbar: true
 intercept_redirects: false

app_dev/php doesn't have any IP restriction. It runs AppKernel with dev environment. Also, AppKernel contains the following line.

$bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();

The main problem could be the HTML markup, but it has both the opening and closing <body> tags. I even tried to remove all the HTML, and just leave it with few HTML tags, without luck.

Is there anything else I could try?
Maybe some files could be missing. How can I check it?

This is not a fresh Symfony installation.

Just in case, If you execute the debug:router --env=dev command, can you see all _wdt and _profiler_* routes ? – Monteith 8/3, 2017 at 9:26

I get debug:router: command not found – Flambeau 8/3, 2017 at 9:37

Maybe try with app/console router:debug --env=dev (it's old name). What's the exact version of your Symfony install ? – Monteith 8/3, 2017 at 9:45

Oh this one works. Yes there is a _wdt and _profiler routes alongside with many other. – Flambeau 8/3, 2017 at 9:49

Make sure you can tick all bullets in this checklist:

You are using the dev mode by accessing the page via app_dev.php (True for you)
The toolbar inserts itself in pages by looking for a terminating </body> tag on your generated page. If you don't have a </body> tag in your page the toolbar will not appear(as in the above answer). Example twig file as a reference:

The line {% extends '::base.html.twig' %} will extend app/Resources/views/base.html.twig which injects default <body>...</body> into your custom twig files.
```
{% extends '::base.html.twig' %}

{% block body %}
  Hello!
{% endblock %}
```

You have enabled the profiler in AppKernel.php

public function registerBundles(){
  $bundles = ...
  if (in_array($this->getEnvironment(), array('dev', 'test'))) {
    $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
  ...
  }
return $bundles;
}

You have javascript enabled.
Thoroughly Check recently added bundles(specially custom ones). Because Cases like this can cause the problem.

Yes, double checked everything. Deleted the whole HTML, left only your example with base.html.twig. I am accessing the page using: project.test/project.dev/public_html/app_dev.php – Flambeau 7/3, 2017 at 14:45

@Flambeau Did you check the latest case I just added? Don't you have any new bundle installed? – Levirate 7/3, 2017 at 14:46

Yes, there is a few custom bundles, but the problem is that the site is not working at all without a few of them. But I got the idea, need to run the site without any custom bundles at all first. – Flambeau 7/3, 2017 at 14:56

Nice job @Flambeau – Levirate 7/3, 2017 at 14:58

Double-check that your <body> tag has a closing </body> tag. In my experience, when the toolbar suddenly disappears it's because the closing body tag is missing due to malformed HTML, or because a controller is returning a Response object with just plain text content.

I had this issue with a large(ish) application where the toolbar wasn't being shown on memory heavy pages. Turns out that my php memory limit was being exhausted. I set the memory_limit in my php.ini file to something that would be adequate and that sorted it.

Same here, it only happened on certain pages. I have twig files rendering lots of data. On app_dev.php It was too heavy and caused the toolbar error 'An error occurred while loading the web debug toolbar.' So solution was to raise the "memory_limit" in the fpm ini file (in my case /etc/php/7.3/fpm/php.ini) – Hodosh 17/1, 2022 at 14:0

if you set the environment as dev it should display debug toolbar at the bottom

edit web/app.php as following;

$kernel = new AppKernel('dev', true);

I recently got an old project in SF3.4 and in my case the debug toolbar didn't show up because of the following keys in config.yml file

framework:
    [...]
    profiler:
        collect: false

I commented on those 2 lines and it works again.

Try to reinstall toolbar

composer remove profiler
composer require --dev profiler

Check the configuration

bin/console debug:config framework profiler
