Redirect loop on wp-admin or wp-login.php

Question

I put together a quick WordPress site locally using MAMP, then checked it into an SVN repo. I then checked it out on to my development server.

I didn\'t change anything

Answer 1

I had a similar issue in my case it was due to restoring a db script that was created with WP Migrate DB. The script had merge tags in like "## DEV URL ##" which i needed to fix before running the script on mysql and pointing the wp-config.php to the correct database.

Answer 2

My problem was that the hardisk was full. Trying to log into the wordpress administration panel was redirecting me to wp-login.php. I was able to log in again the moment I deleted some files.

Answer 3

I was getting DoS pages when trying to publish in my WP site. I found advice that changing permissions in the function.php file to 600 could solve the issue, also to add to that file a script snippet . It was a WP help page. I was able to get to the publishing in a work-around way. Still have the DoS when I try to open the editor.

Answer 4

In my case it was Apache's DirectoryIndex issue. The wp-admin was being accessed by wp-admin/index.php but not with wp-admin and showing ERR_TOO_MANY_REDIRECTS.

It sounds like Apache's DirectoryIndex may be set "incorrectly". Try resetting this at the top of your .htaccess file:

DirectoryIndex index.php

Answer 5

If you are useing Cloudflare, from SSL/TLS tab of your Cloudflare account, select Full encryption. It will solve the issue.

Answer 6

If you're using Cloudflare you might want to try adding this to the TOP of your wp-config.php file:

define('WP_SITEURL', 'https://www.example.com');
define('WP_HOME', 'https://www.example.com');
define('FORCE_SSL_ADMIN', true);
define('FORCE_SSL_LOGIN', true);
if(isset($_SERVER['HTTP_CF_VISITOR']) && strpos($_SERVER['HTTP_CF_VISITOR'], 'https')){
  $_SERVER['HTTPS']='on';
}

It's important that you add it to the top of the wp-config.php file or you'll end up with "Sorry, you are not allowed to access this page" error messages.
