Wordpress Website 101    

Hi everyone,

I'm not sure if the course is over yet or not, but I completely messed up my wordpress blog and was wondering if anyone could help me out! I was trying to change the URL that my blog is hosted on, and I completely screwed things up and I cannot even login to wordpress anymore. I was following these directions in order to change my wordpress to be hosted at a subdomain:

"In order to move your wordpress blog to another subdirectory however, it is best to check the wordpress support article, Moving WordPress: http://codex.wordpress.org/Moving_WordPress

You can follow the instructions under { Moving WordPress Within Your Site }

Moving the WordPress files from one location on your server to another - changing its URL - requires some special care.

Here are the step-by-step instructions:

1. If you will be moving your WordPress core files to a new directory, create the new directory.
2. Login to your blog.
3. Go to the Administration > Settings > General panel.
4. In the box for WordPress address (URI): change the address to the new location of your main WordPress core files.
5. In the box for Blog address (URI): change the address to the new location, which should match the WordPress address (URI).
6. Click Save Settings.
7. (Do not try to open/view your blog now!)
8. WordPress 2.0 only: Delete the folder wp-content/cache.
9. Move your WordPress core files to the new location. This includes the files found within the original directory, such as http://example.com/wordpress, and all the sub-directories, to the new location.
10. If you are using Permalinks, go to the Administration > Settings > Permalinks panel and update your Permalink structure to your .htaccess file, which should be in the same directory as the main index.php file.
11. If you have problems with missing images that you've uploaded, you need to change the path to the images on every post directly on your SQL database. For this, follow the instructions on Tamba2's Tutorial "Moving your weblog inside your PC".
12. You must also check and edit 'store uploads folder' under Settings-Miscellaneous or all your new uploads will continue to go into the old folder.
13. Existing image/media links uploaded media will refer to the old folder and must be updated with the new location.

It is important that you set the URI locations BEFORE you move the files. "

The subdomain I was trying to use ended up not being correct/a real domain. I thought I had changed everything in my wordpress blog back to the original domain, but when I try logging in to my wordpress account, I get this error message: "Server not found." I tried finding help forums on what to do, and I could find was to log in to phpMyAdmin and navigate to the wp_options table and change the url. The problem is, my url shows up as the right one when I do that.

Does anyone have any idea what I can do to fix this? My end goal is to completely change the domain that my blog shows up on, but I have NO IDEA how to do this without screwing everything up! Now I cannot even log in to my blog and when I visit the domain name that it should show up on, all of the pictures and posts are there but all of the design and formatting is gone!

Any ideas anyone has would be appreciated!
