Importance of WordPress multisite
Nowadays, WordPress Multisite has become popular among web owners. This is because it provides a way for multiple individual sites in a single WordPress installation.
Moreover, a user can handle all the websites through a single dashboard. That is, it avoids the use of multiple logins and a single super admin can manage everything. This is the main advantage of setting up a multisite.
Moreover, a large number of sites can be added under one WordPress. However, the sites must have similar functionality. Because it does not apply to sites that are widely different in terms of plugins, themes, and customization.
What is a redirection loop?
Recently, one of our customers approached us with a login problem in the WordPress admin panel. He had a WordPress multisite setup.
Whenever he tried to log in to the admin panel, it returned to the same login screen. This reverting back of the wp-admin login page is a redirection loop.
The major causes for this error are invalid cookies, faulty plugins and bad configuration of the .htaccess file.
How we fix WordPress multisite redirect loop?
Now, let’s have a look at the reason for WordPress multisite redirection and see how our Support Team solve it.
An invalid cookie
An invalid cookie on websites can cause a redirect loop. WordPress uses cookies for user verification and session management. It also enables caching.
But the problem arises when the cookies use old information or rely on old website files.
Similarly, when a cookie is created, it includes the name, some sensitive content, and the path. Therefore, if the resetting of cookies does not take place, it leads to redirect loop error.
So, to automatically clear the browser’s cookies, we add the following line in wp-config.php
define('ADMIN_COOKIE_PATH', '/');
define('COOKIE_DOMAIN', '');
define('COOKIEPATH', '');
define('SITECOOKIEPATH', '');That fixes the problem.
Bad rule in .htaccess
In addition, another possibility for this error is the bad setting in the .htaccess file. This will make the WordPress admin go into a redirection loop.
Therefore, we disable the current .htaccess file and create a new one.
To disable it, we login to the server as a root user. Then, select the .htaccess file for the corresponding domain. Later take a backup of it.
mv .htaccess .htaccess_backAfter that, we create a new .htaccess file for the domain with the correct base directory.
Faulty plugins
Sometimes, a faulty plugin used on the website can cause a redirect loop. In such cases, we check the recent updates, identify the faulty plugin and fix the error.
