子文件夹中的 Wordpress /wp-admin 重定向问题

Question

A Wordpress website is installed in a subfolder, let's call it my_site

I need the website to load subfolder contents when the domain name is accessed (let's say it's https://example.com ), and thus, I have set up my .htaccess file like so:

RewriteEngine on 
RewriteCond %{HTTP_HOST} ^(www.)?example.com$
RewriteCond %{REQUEST_URI} !^/my_site/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /my_site/$1 
RewriteCond %{HTTP_HOST} ^(www.)?example.com$ 
RewriteRule ^(/)?$ my_site/index.php [L]

Now, in terms of content and the website overall - everything works correctly. The issue is with trying to login into the WP dashboard by going directly to https://example.com/wp-admin

Browser does load the standard WP login screen but upon entering my credentials, the same login form shows up - it's like I simply refreshed the page.

Both upon first going to the https://example.com/wp-admin URL and after trying to login, when I experience the "browser refresh-like" behavior, the URL string in browser is set automatically to:

https://example.com/wp-login.php?redirect_to=https%3A%2F%2Fexample.com%2Fmy_site%2Fwp-admin%2F&reauth=1

Same URL decoded:

https://example.com/wp-login.php?redirect_to=https://example.com/my_site/wp-admin/&reauth=1

So clearly the problem is that my_site is appended inside the redirect_to parameter, but I have no idea how to get rid of it.

Any help is greatly appreciated!

PS The WP_HOME and WP_SITEURL variables are set in wp-config.php like so (to target both http and https):

$hostname = isset( $_SERVER['HTTPS'] ) && strtolower( $_SERVER['HTTPS'] ) == 'on' ? 'https' : 'http';
$hostname .= '://' . $_SERVER['HTTP_HOST'];
define( 'WP_HOME', $hostname );
define( 'WP_SITEURL', $hostname );

Hey all you need to remove (www.)? from RewriteCond like so

RewriteEngine on 
RewriteCond %{HTTP_HOST} ^example.com$
RewriteCond %{REQUEST_URI} !^/my_site/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /my_site/$1 
RewriteCond %{HTTP_HOST} ^example.com$ 
RewriteRule ^(/)?$ my_site/index.php [L]

second, if you decode your URL via URL Decoder

https://example.com/wp-login.php?redirect_to=https%3A%2F%2Fexample.com%2Fmy_site%2Fwp-admin%2F&reauth=1

you will notice my_site which is the root cause that does not allowing to redirect to wp dashboard because in htaccess you restrict to example.com .

Once you remove my_site%2F from URL and re-submit login form you will definitely redirect to dashboard.

Now all you need to config redirect URL to wp-admin such that it does not contain actual wordpress folder

i had the same problem. You probabably have changed to https? the solution is in the database.

wordpress official site

In some situations, your blog can be seen from inside your domain, but not outside. Following the instruction above about changing the wp-options MySQL table might still result in login failure.

In this event, double-check your wp-options table siteurl (WordPress address URL) and home (Blog Address URL) values to make sure they reference the same base externally available address; ie, http://blog.yourdomain.com . The standard install may set them to your local (internal) host name, such as http://servername

Another issue may be if you are redirecting using .htaccess from a non-www url prefix to a www while you have the wp-options table siteurl (WordPress address URL) and home (Blog Address URL) set with non-www prefix. Consequently this would create an endless loop which you need to avoid. One way is to disable the .htaccess redirection temporarily by placing # before the line or eliminating the entries entirely and trying to Login again. Advanced users may want to adjust the wp-options table siteurl (WordPress address URL) and home (Blog Address URL) through the database. Notice that this issue can also occur if you are redirecting from www to non-www but have your wp-options table siteurl (WordPress address URL) and home (Blog Address URL) set with a www url prefix.
