Wordpress admin doesn't load css / js

Question

I have a problem with an administrator on a Wordpress site. I looked through cross-industry networks and saw many other people with the same problem, but did not have a specific solution. The administrator displays the following:

And when I check it, I get 500 (Internal server error) for both load-styles.php and load-scripts.php

Does anyone know what and how to fix?

Answer 1

In wp-config.php before require_once add below code to file:

 define('CONCATENATE_SCRIPTS', false); 

Answer 2

Just for everything to be in one answer, this worked for me:

 define('FORCE_SSL_LOGIN', true); define('FORCE_SSL_ADMIN', true); define( 'CONCATENATE_SCRIPTS', false ); define( 'SCRIPT_DEBUG', true ); 

After refreshing the page, it looks fine, perhaps after logging in again, set the SCRIPT_DEBUG parameter to false.

Do not forget about the last two settings if you use plugins for debugging or site optimization, although such plugins can override these parameters.

Answer 3

CSS was not loaded in my case (with WordPress 3.7.1) due to an encoding problem.

Fix UTF-8 encoding by replacing the corresponding line in wp-admin/load-styles.php with:

 header('Content-Type: text/css; charset=UTF-8'); 

Answer 4

Put define('SCRIPT_DEBUG', true); in wp-config.php and debug through the console. It will tell you which file was not found at page load time.

Answer 5

In the wp-config.php file you can add - define ('SCRIPT_DEBUG', true); This solves the problem, but it is not recommended to leave this config to true during operation.

Hope help

Answer 6

I had a similar problem with a new installation of Wordpress that required redirecting to a temporary URL.

My solution was to make sure siteurl and home url had http: // at the beginning of the URL.

Hope this fixes this.

Have you tried uninstailling and then reinstall Wordpress?
