Wordpress upgrade to 2.6

I manage to upgrade my Wordpress blog here from 2.5.1 to 2.6, which was quite disappointing to me as I took nearly an hour just to upgrade it.

For those who are having the common problem that I had, which was "Sorry, page not found" or similar to that when you're logged in to the administration area, you have made a huge mistake during the upgrade. Therefore, it is very important to backup your files and your database before you make any move in upgrading to the latest WP 2.6

The two main simple steps that you need to do take BEFORE the upgrade:

1. Delete wp-admin folder
2. Delete wp-include folder

Once you're done, upload/unzip the latest WP and overwriting the existing files in your server. You will be able to upgrade without any errors after that.

Before this I usually don't delete the folders or anything. What I do is just overwriting the files in that 2 folders. For now it won't work like that any more I guess lol.
