复制安装后，Wordpress wp登录不可用

Question

First: I know that this question is existing in many variations and that there have been many answers but none of the solutions worked for me.

I have a working instance of WP running on my server, but I want to work on a new design and parallel run the old site. So I created a new subfolder neu on my server and copied all the WP-Files I had in this folder. I Also created a new database and imported my old database-file via sql inside the new database. Before I have imported the sql file I used the search/replace function in my editor and replaced www.myurl.de/ with www.myurl.de/neu/. I changed the data in the wp-config file and added

define('WP_HOME','example.com');
define('WP_SITEURL','example.com');

to my wp-config.

When I go to the new site i can open the front end sites, but when I try to go to the login page I get a 404.

So I am wondering what else could be the problem. The only thing that I noticed is that when I go to my database with phpMyAdmin and open the wp_options table, the siteurl is www.usersite6.de, but in the original installation it's the same, so I guess that this won't be the problem.

the site is: http://www.nrc-makler.de or http://www.nrc-makler.de/neu

Answer 1

I decided to create a new subdirectory and do everything from scatch again, because in my try before I did everything just "somehow" "somewhere". Now it works for me, so here is what I did, if somebody has the same problem.

1. Copied the files to new subfolder
2. created new DB and imported my "old" DB
3. used SQL to update the urls in my new DB

UPDATE wp_options SET option_value = replace(option_value,'old-url','new-url') WHERE option_name = 'home' OR option_name = 'siteurl'; UPDATE wp_posts SET post_content = replace(post_content,'old-url','new-url'); UPDATE bmccmps7_postmeta SET meta_value = replace(meta_value,'old-url','new-url');

1. updated htaccess

   # BEGIN WordPress
   

   RewriteEngine On RewriteBase /new-subdirectory/ RewriteRule ^index.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /new-subdirectory/index.php [L]

2. added relocate function to my wp-config (right before the "That's all, stopp editing!"-line

   define('RELOCATE',true);

3. Logged in to www.new-url/wp-login with old user data - and it wordked for me
