I have the following error in my apache2 error log (Ubuntu 18.04, local LAMP dev environment, PHP7.3), that I believe is causing a The page isn’t redirecting properly error:

I have been search online for a few hours, but have not found anyway to resolve this error.

The contents of my /etc/hosts file is as follows:

127.0.0.1   localhost 
127.0.0.1   localhost.example.org   *.localhost.example.org
127.0.0.1   someothername.org   www.someothername.org
127.0.0.1   blog.localhost.example.org
127.0.0.1   seminar.localhost.example.org

#The line below is for shared folder access. DP Edit.
127.0.0.1   machinename.local

My apache2 virtualhost file says:

<VirtualHost *:80>

    ServerName localhost.example.org 
    ServerAlias localhost.example.org 
    
    # If this is the default configuration file we can use: 'ServerName localhost' or also 'ServerAlias localhost'.

When I run apache2ctl configtest, I also get the following error which may or may not be related:

Action 'configtest' failed.

NOTE: /etc/ssl/private/ssl-cert-snakeoil.keyDOES in fact exist.

My wp-config file has the following values:

/* Multisite */

The output of curl --insecure --head https://localhost.example.org is as follows:

HTTP/1.1 302 Found
Date: Fri, 14 Aug 2020 02:45:51 GMT
Server: Apache/2.4.29 (Ubuntu)
Location: https://localhost.example.org
Content-Type: text/html; charset=UTF-8

It appears to be redirecting to the correct location, even though I am getting the redirection error.

To ensure that the error is NOT being caused by wordpress, I have tried the following:

  1. disabled all plugins = redirecting error still present NOTE: no new htaccess was generated by wp
  2. used db query to update siteurl value to match localhost UPDATE wp_options SET option_value='https://localhost.example.org' WHERE option_name='siteurl' = redirecting error still present
  3. updated wp-config to reflect define('WP_HOME','https://localhost.example.org'); define('WP_SITEURL','https://localhost.exmple.org');

NOTE: I previously had modsecurity and the evasive modules installed, but I have since disabled, uninstalled, and purged any trace of them.

Any ideas?

  • I assume that you are trying to type https://localhost.example.org into the URL bar of a browser on local machine? What does CURL report for the Location: header if you use curl --head https://localhost.example.org on the command line? – Stephen Ostermiller Aug 13 at 12:09
  • @StephenOstermiller the output is curl: (51) SSL: no alternative certificate subject name matches target host name 'localhost.example.org' – yupthatguy Aug 13 at 13:23
  • localhost.example.org/phpinfo.php works. The WP site connects to the DB (tested with a script). Could the problem be .htaccess file? – yupthatguy Aug 13 at 13:26
  • You can use the curl --insecure --head https://localhost.example.org to bypass the SSL error and see what the redirect is. Are you doing any redirecting in the .htaccess file? If so, edit your question and post the contents of your .htaccess as well. – Stephen Ostermiller Aug 13 at 15:47
  • @StephenOstermiller I have edited the question ad added my htaccess file. It appears that the redirect is going to correct location. :-/ – yupthatguy Aug 14 at 5:41

This might help?

In your apache config, you see these lines:

<VirtualHost *:80>
...
</VirtualHost>

This means that the config in between matches for all hostnames on port 80 (HTTP non-SSL).

But...

In your wp-config file, these lines:

define( 'NOBLOGREDIRECT', 'https://localhost.example.org' );
define('WP_HOME','https://localhost.example.org');
define('WP_SITEURL','https://localhost.example.org');

Are forcing your Wordpress install to use SSL even if you initially access on non-SSL. Additionally, in your htaccess you appear to be running the plugin W3TC which is also forcing SSL

RewriteCond %{HTTPS} =on

The reason all of that is relevant is that ultimately, the setup will force SSL to be used between client and server at all times, which then means your virtualhost config as pasted in your answer is irrelevant. Instead, the Apache setup will look for the first virtualhost that matches with traffic on port 443, e.g.

<VirtualHost *:443>

This may be in an entirely different config file, such as in your case: /etc/apache2/sites-enabled/default-ssl.conf.

So its possible that the reason this is not working is because that other config file doesn't have the right hostname/config for your purposes. So you may have two options:

  1. Don't use SSL for the moment, until you are sure all else works
  2. Use SSL but make sure your config is correctly setup for traffic on port 443 and you have a valid SSL cert.

If you don't have a valid cert, at least you will get a different browser error.

  • Thanks for the effort..But to relive the bottleneck I already restarted / finished my migration process, completely avoiding this problem, but I accept your answer :-) – yupthatguy Aug 17 at 14:30
