I have just been moving my blog to new host. Everything was fine after I did it as described at Wordpress Codex except admin panel.
When I was trying to login to Dashboard I got 404 error. There is one very simple solution for it. When I was moving files from my old host my ftp client set chmod of /wp-admin/ directory to 775. It won’t work with this permission. All you need to do is to change it to 755 and it should be working again.
If you have decided to move a copy of your wordpress to other host propably you will have problem with your mysql login details. Even if mysql database name, login and password are same – propably you will have to change login host (until it is not localhost :) ). It is very easy to do. All you need to change after you copy WordPress script to your new account is to edit wp-config.php file. Open it in any text editor (Notepad would be ok), find and edit following lines:
define('DB_NAME', 'put_db_name_here');
define('DB_USER', 'put_db_login_here');
define('DB_PASSWORD', 'put_db_password_here');
define('DB_HOST', 'put_mysql_host_here');
And that’s all :)

Since I have upgraded a Wordpress to version 2.8 I have seen new comments counted by Akismet plugin but nothing in spam queue nor any comments to approve. It looked very strange for me!
I have logged out from my blog admin and tried to post a comment. After submitting it I saw a blank page!
The worst thing was that I have not found any solutions in google (and people say that google always knows the answer :)) – so I decided to upgrade K2 Theme… But there is now new release on their main page!
But wait! There is a solution! (or I would not write this post :)) After some googling (ok… please forget what I wrote about google before… :D) I have found K2 nightly build subpage… All you need to do to fix this issue is to upgrade K2 with nightly build. It can be downloaded from: http://getk2.com/nightly/.
I have decided to download last RC8 version (k2-1.0-RC8-revision-807-2009-07-13.zip). And now you can test if comments are working again :)
