Moving to a new host

First thing to check are whether the username and password are the same (not just the database name)? If not, change them.

Also, whether you must now reference your database host (DB_HOST) in config.php as “localhost” or your domain name or something else.

If your blog is *now* in a folder, that may need to be changed in the database files (through phpmyadmin).

The other thing is that setting up the site as an add-on domain — to what? to a main domain? Or just as an additional web hosting account? These may factor in to how you must reference the database.

Thanks for your response. Very good question. Here’s how it works. I have moved one domain over (not a blog) already, and things seems easy enough.

1. All files go into a folder called public_html. The main domain resolves to that folder. Each addon domain goes into its own folder underneath public_html. In the previous case, changing the DNS to point to my new hosts DNS servers did the trick

2. In my current blog I have the following structure
/
index.php
blog/

All my files are under blog, but going to xyz.com reads the index.php file which just points to the blog/ (something I would love to change but too much content to take the risk now)

3. The database part is what I am worried about. I am no MySQL guru. Are the username and password in wp-config.php the same as the admin username and password for my wordpress account? They are a random string in wp-config.php. I presume I can use regular text to change things?

Thanks for all the help

I redid everything from scratch and still the same problem

Here is my wp-config.php. Everything is the same as before, except that here the db name and username have a pre-fix that cpanel automatically attaches when I created the empty db and a new user for it. I typed in the username and password manually into the file (probably not the right thing to do either)


<?php
define('WP_CACHE', true); //Added by WP-Cache Manager
// ** MySQL settings ** //
define('DB_NAME', 'blog_db_name'); // The name of the database.
define('DB_USER', 'username'); // Your MySQL username
define('DB_PASSWORD', 'password'); // ...and password
define('DB_HOST', 'mysql'); // 99% chance you won't need to change this value
// Change the prefix if you want to have multiple blogs in a single database.
$table_prefix = 'wp_'; // example: 'wp_' or 'b2' or 'mylogin_'
// Change this to localize WordPress. A corresponding MO file for the
// chosen language must be installed to wp-includes/languages.
// For example, install de.mo to wp-includes/languages and set WPLANG to 'de'
// to enable German language support.
define ('WPLANG', '');
/* Stop editing */
define('ABSPATH', dirname(__FILE__).'/');
require_once(ABSPATH.'wp-settings.php');
?>


From what I can gather, the addon domain is not an issue. Since I am not changing the blog structure, I suspect its the database. Any troubleshooting suggestions?

define('DB_HOST', 'mysql'); – if it is NOT the usual “localhost”… very unlikely to be the same on two different servers/host!

Thanks, that seemed to help… and changed the errors

Now I am getting a bunch of cache related errors like the following


Warning: fopen(/home/user/public_html/domain_name/blog/wp-content/cache/wp_cache_mutex.lock) [function.fopen]: failed to open stream: No such file or directory in /home/user/public_html/domain_name/blog/wp-content/plugins/wp-cache/wp-cache-phase2.php on line 79

1. Do you use WP-Cache plugin?
2. Did you copy all your plugins and theme’s over?

1. Yes I do
2. Not all my themes, since there were a few I never used. I guess I should. Plugins, yes. I had not copied the content of the cache folder (under wp-content), but I just did. However, the specific file that is giving the error is not there.

Just for the record here is the complete error message

BUMP .. Anyone?

An update:

I redid the blog move, this time, turning off a few plugins, including wp-cache. I changed my nameservers over. The front page looks OK, but when I click on individual links, I am getting errors like

The requested URL /blog/archives/ was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

What could be causing this?

Thanks

Check out troubleshooting tips at the Permalinks page.

New move? make sure you’ve been to that page and re-saved your current settings.

Didn’t improve? Confirm with host that mod_rewrite and AllowOverrides are on and properly enabled.

A number of people have successfully moved to my current host, so I suspect it does work, and Podz (whose tutorial I followed) also hosts there.

I did create a .htaccess file. Lets see how it works.

I am not sure what you mean by the re-saving settings part? Yes, this is a completely new host (same domain name).

Some more messages that I am seeing.
