In my .env file, I have specified my app environment to be dev and debug to be true like so:
APP_ENV=dev
APP_DEBUG=true
In my config/packages/dev/web_profiler.yaml file I have the following:
web_profiler:
toolbar: true
intercept_redirects: false
framework:
profiler: { only_exceptions: false }
The routing within config/routes/dev/web_profiler.yaml seems to be fine:
web_profiler_wdt:
resource: '@WebProfilerBundle/Resources/config/routing/wdt.xml'
prefix: /_wdt
web_profiler_profiler:
resource: '@WebProfilerBundle/Resources/config/routing/profiler.xml'
prefix: /_profiler
So when I run the server with symfony server:start everything is fine, but the profiler doesn't appear. Did I miss something that enables that feature within Symfony?
To clarify, the page is outputting a proper HTML page with the appropriate content. There is just no profiler showing up.

It's very hard, if not impossible, to debug this for you remotely. The exact problem is tied to something specific in your local setup, and someone without access to your project would not have a chance to see exactly what is wrong.
Some general and specific troubleshooting advice for your situation:
While unusual, the installation could be borked. Make sure your profiler package is alright.
First remove it (composer remove profiler), and then install it again: composer require --dev profiler).
Use Symfony's console command to verify your configuration.
First for the built-in profiler:
$ bin/console debug:config framework profiler
Which should return something like this:
Current configuration for "framework.profiler"
==============================================
only_exceptions: false
enabled: true
collect: true
only_master_requests: false
dsn: 'file:%kernel.cache_dir%/profiler'
And then for the profiler toolbar:
$ bin/console debug:config web_profiler
Which should return something like:
Current configuration for extension with alias "web_profiler"
=============================================================
web_profiler:
toolbar: true
intercept_redirects: false
excluded_ajax_paths: '^/((index|app(_[\w]+)?)\.php/)?_wdt'
Check how the Profiler service will be instantiated:
$ bin/console debug:container profiler --show-arguments
Expect something like this:
Information for Service "profiler"
==================================
Profiler.
---------------- -------------------------------------------------------------------------------------
Option Value
---------------- -------------------------------------------------------------------------------------
Service ID profiler
Class Symfony\Component\HttpKernel\Profiler\Profiler
Tags monolog.logger (channel: profiler)
kernel.reset (method: reset)
Calls add, add, add, add, add, add, add, add, add, add, add, add, add, add, add, add, add
Public yes
Synthetic no
Lazy no
Shared yes
Abstract no
Autowired no
Autoconfigured no
Arguments Service(profiler.storage)
Service(monolog.logger.profiler)
1
---------------- -------------------------------------------------------------------------------------
And then for the web_toolbar:
# bin/console debug:container web_profiler.debug_toolbar --show-arguments
For something like this:
Information for Service "web_profiler.debug_toolbar"
====================================================
WebDebugToolbarListener injects the Web Debug Toolbar.
---------------- ------------------------------------------------------------------------
Option Value
---------------- ------------------------------------------------------------------------
Service ID web_profiler.debug_toolbar
Class Symfony\Bundle\WebProfilerBundle\EventListener\WebDebugToolbarListener
Tags kernel.event_subscriber
container.hot_path
Public no
Synthetic no
Lazy no
Shared yes
Abstract no
Autowired no
Autoconfigured no
Arguments Service(twig)
2
Service(router.default)
^/((index|app(_[\w]+)?)\.php/)?_wdt
Service(web_profiler.csp.handler)
---------------- ------------------------------------------------------------------------
(Note the 2, which enables the toolbar).
The web debug toolbar is injected during the kernel.response event. Check that the callback is appropriately hooked:
$ bin/console debug:event-dispatcher kernel.response
Which will return something like this:
Registered Listeners for "kernel.response" Event

Notice item #7, which is the Profiler collector (which among other things will include the X-Debug-Token header in the response, which will be later checked by the Web Debug Toolbar, which is item #8 in the above listing.
You'll have to focus on that specific part to find out why it is failing. Maybe some other bundle interfering? A problem with one of the configuration files?
If the rest works, the bar is actually rendered on the HTML, but now shown because you get a "mixed content" error, it's likely because you are accessing the site via a reverse proxy or load balancer, the site is not correctly configured, and Symfony has trouble figuring out the right connection scheme. Make sure you check the docs for connecting behind a proxy, and follow them thoroughly.
... but still not working? Well, that's weird. Make sure that your returned template has a </body> tag, and that the returned response has text/html content-type. But if all of the above checks out... it should work.
In a comment, you say that framework.profiler.collect is set to false when performing these checks.
Set it to true by changing config/packages/dev/web_profiler.yaml like this:
framework:
profiler:
only_exceptions: false
collect: true
