Joomla Editor: select image looks ugly (no css?)

Question

When I want to insert an image in an article, the modal where I select an image is very ugly. It seems there is no CSS which makes the modal more beautiful.

In my index file I've got the following CSS files:

<link rel="stylesheet" href="<?php echo $this->baseurl ?>/templates/system/css/system.css" type="text/css" />
<link rel="stylesheet" href="<?php echo $this->baseurl ?>/templates/system/css/general.css" type="text/css" />
<link rel="stylesheet" href="<?php echo $this->baseurl ?>/templates/<?php echo $this->template ?>/css/template.css" type="text/css" />

I'm using Joomla! 3.6.5. Does anyone know why this happens?

Some helpful troubleshooting steps:

1. Clear all caches - On your Browser and Joomla's. Also check if your hosting provider has any other persisting cache mechanisms in place.

2. To escape from the "... Cache Storage is not supported on this platform issue", you can edit directly your configuration.php file and set the $cache_handler variable to another setting, like 'file'.

   public $cache_handler = 'file';
   

3. ... and could also help if you set the cache off temporary:

   public $caching = '0';
   

4. If with all caches cleared, you still get the broken layout issue - then this likely is caused by a php error. A php error (fatal error somewhere) will stop the execution which could lead to incomplete rendering - broken layouts, missing assets etc.

Php errors can be produced from corrupted files, an incomplete update, or other old outdated code somewhere, or even by files that should be where they are - think also a hacked site - Enable error reporting - make sure that any errors are printed/logged in any case - and start debugging to see if this is the case.
