Question

wp site not showing pages, posts, images, favicon etc

Posted April 4, 2017 9.9k views
MySQLWordPressUbuntu 16.04

Hello, there!

I am testing a second wp site in my droplet.
I restored database and wp-content, but not everything shows up.
Plugins are there all activated. The theme is also active. But no pages or posts or images of the original site i am trying to migrate. It seems the site is not accessing its correct database. The articles showing are of the on board theme, ‘hello world’.

Some idea?

You need to edit the /wp-config.php in the root folder to ensure it points to the database and table you’ve just restored.

Seems like you’ve setup a default WordPress installation, which creates the default database, but did you overwrite that with the restore or did you restore into a different database?

    Thanks!

    The default database is the one i chose the name when installing wp, right? I restored to a different database and changed the wp-config.php to the restored one.

    The correct database is there. When i command SHOW DATABASES; it shows up. The user has privileges granted also. The /wp-config.php is also all set up.

    Thanks for your help!

Hi!

I campared the two config files one of my alive site in a shared host and the one i am installing in my droplet. The names of the table prefix were different. So i ajusted the name i the config file of my wp site and it is now showing everything.

But, i have a new problem: i can’t login anymore in the wp-admin.

I went to the config file again and reset the password. But it did not work.

:(

    Ahh, yeah, that’s a tricky one to catch if you’re not used to play with the internals of WordPress.

    I don’t know what you use to view/edit your database with, but otherwise I would recommend www.adminer.org

    Goto your database, then the table called prefix_usermeta (where prefix would be whatever is your prefix).

    Now you’ll have to look in the column meta_key and find the row with something that would be oldprefix_capabilities (where oldprefix is whatever you had before).
    The meta_value of that row would probably be a:1:{s:13:"administrator";s:1:"1";} if you only had created one user that has administrator rights.

    Now change the oldprefix_capabilities to prefix_capabilities and that should fix it.

    Again, it might be a little confusing with prefix/oldprefix, but since I don’t know what your real prefix names are, then I can’t use those as examples.

      If you had multiple users, then you need to change the meta_value for each user. No matter if they were administrators or not - otherwise they cannot login either.
      You can see the user ID in the user_id column. Normally the first user you created has 1 as ID, which is automatically created as administrator. But you might have changed that later if you added other users or deleted the first user created.

      Great!!!!!

      The prefix of my fresh wp install was ‘wp’.
      The prefix of my wanted database is 'wordpress      ’

        Okay, you can do it manually - and maybe learn a little from going around in Adminer and the database.
        Or you can run this in your WordPress database, which should automatically search for wp_capabilities and replace it with wordpress_capabilities:

        UPDATE `wordpress_usermeta` SET `meta_key`='wordpress_capabilities' WHERE `meta_key`='wp_capabilities';

          Come to think of it, there’s another key which might need updating too.
          It’s called PREFIX_user_level - I’m not 100% sure if it’s required, so start without it to begin with otherwise run this to fix it.

          UPDATE `wordpress_usermeta` SET `meta_key`='wordpress_user_level' WHERE `meta_key`='wp_user_level';

Hi, i am trying to open my database, USE 'xxx';, but mysql says ‘database changed’.

This is actually my second wordpress install. My main install is this one www.radha.org.br. So, i have to adjust only this specific database.

    @Areku Remember the @ otherwise we don’t get notified.

    Just use Adminer, so you have a graphical interface, which is easier to work with.
    How many different database do you have?

    Yes, you need to adjust the settings only for the specific database, where you’re having problems with that restored WordPress.

    I cannot see which database you’re using on your site - that’s only visible in the wp-config.php file of the root of that site.

Firstly, i am very grateful to your help.

I just asked in Adminer’s forum if they have a tutorial to install it in my droplet. I found something, but for apache users.

I have two databases for real and one ‘default’, justly this one i created when installing the second wp site, that i shall delete.

The site radha.org.br is alive.

The site arun.com.br is the one i am migrating to my VPS. It is alive in a shared hosting. I know the name of its database. But when i make the command USE xxx; Mysql says 'database changed’. So, i can not begin anything.

Let’s remake the journey. if you still are available for that. :) Thanks a lot.

I installed a second wp site in My VPS, creating a database ‘default’. This install was made to bring my other domain in. Then i brought my desired domain’s database and wp-content in. This restored database brought in did not match with the configuration of the existing default wp-config.php file in the line 'table prefix’.

The table prefix in the freshed installed default wp-config.php file was set to 'wp_', which i changed to 'wordpress_', to match the configuration of the wp-config.php file from where this desired database came, in which the table prefix was 'wordpress_'.

Then the site showed as it should. :)
But then it was not possible to login in wp-admin. :(

Examining the Adminer i see that both tables you mentioned have 'wordpress_’ as table prefix in the actual configuration. What i think would be right. But, I tried to change it to its old value just see if it would result in anything positive. One first, testing, and the other. I tested it and still i couldn’t login in wp-admin.

I changed back the tables to their original values in Adminer and came here to report to you.

All the best,

  • Maybe the solution would be to redo the whole process, re-exporting the desired database with the table prefix to match the default one. I would have to learn how to do that in phpmyadmin.

    Hehehe, of course we can redo everything :-)

    Which domain is the one you’re trying to move - arun.com.br ?
    Have you migrated the domain yet ? (EDIT: Meaning have you changed the DNS)

    What happens when you try to login in wp-admin ?

Yez. I am bringing arun.com.br to my droplet. But first i need to check if all is working in order to change DNS.

So i have two admins in my droplet:
In radha.org.br all is working and i login in radha-wp-admin successfully. in arun.com.br (testing mode via changing my local hosts file) i am not able anymore to go into arun-wp-admin after database adventure.

Thanks!!

    Okay, let’s get everything cleaned up.

    1. Create a database called arun.
    2. Import your data dump into that database. (what’s the prefix?)
    3. Now goto the web-root of the site (I’m guessing /var/www/arun.com.br) and edit wp-config.php
    4. In wp-config.php, make sure to update the username and password, but also set the following define('DB_NAME', 'arun'); and $table_prefix = 'wordpress_'; (has to match the prefix from the data import).

    So no changing anything in the database, just do a straight import and let’s see where that leaves us.

    If it’s still complaining about username/password, then run the following query:

    USE `arun`; UPDATE `wordpress_users` SET `user_pass`=MD5('change-this-password') WHERE `ID`=1

    And then try to login with whatever the username is and password change-this-password

Thank you so much!

1) Ok. the database ‘arun’ is already there. Actually it is the original name of the first database created to arun.com.br’s wp.
2) I don’t know the command to import the *sql.gz INTO database arun.
2.1) The prefix used in my shared hosting wp is 'wordpress’ The prefix used in this new wp install in my droplet is 'wp’.
3) and 4) OK.

I shall delete this one database that did not work, right? And leave the wp-content, i guess…

Fine, @hansen

I’ll have a nice sleep now after whole day of commands. I close my eyes and keep commanding lines into my dreams. Funny.

All the best

    1. Remove the database arun and create it again, so we’re sure it’s clean.

    2. Use Adminer to import the data to arun.

    We will continue to use wordpress_ as the prefix, so we don’t need to modify anything.

Hello!

Did all as instructed. It looks like this in Adminer:

information_schema          ?               ?
arun                                    utf8_unicode_ci ?   ?
bddarunwp                           utf8_general_ci ?   ?

Any additional step now?
