AH01797: client denied by server configuration Wordpress Plugin JS Files in Apache Web server

Question

I am having problems while trying to add a post to a Wordpress website. This site works in schematic using fastcgi, inside a subdomain like email.medialab.ufg.br. The issues seem to be related to accessing .js and .css files from a Wordpress plugin. Here is the error reported:

[Fri Jun 08 13:45:44.000087 2018] [access_compat:error] [pid 32401] [client 200.137.195.149:63863] AH01797: client denied by server configuration: /home/l3p/apache_sites/email.medialab.ufg.br/web/wp-content/plugins/advanced-custom-fields-pro/assets/inc/timepicker/jquery-ui-timepicker-addon.min.js, referer: https://email.medialab.ufg.br/wp-admin/post-new.php?gutenberg-demo

The site's .htaccess file has the following configuration: **

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

And the virtualhost file the following configuration:

<VirtualHost *:80>

                                DocumentRoot /home/l3p/apache_sites/email.medialab.ufg.br/web

Any idea what might be going on? How to fix the problem?

Answer 1

I recommend checking for more information in your logs. I had a similar issue. When I just searched for the 503 error, I only got the error message you have. When I looked at messages around it, I saw:

mod_lsapi: [host <domain_name>] [req GET / HTTP/1.1]
    Could not connect to lsphp backend: connect to lsphp failed: 110

My server uses cPanel for management. Going into cpanel and manually selecting the PHP version fixed this. I'm not sure the same will be true for you, but the error messages might help you narrow in on the problem.
