HELP! My Website Is F*cked After Upgrading to WP 2.6!

I don't know if you can apply this method, it happened on my computer (localhost)

If you can access the admin area (if not, try the next step),
- deactivate all plugins,
- change the theme to wordpress default,
From the ftp (file manager):
- In wordpress folder, delete "wp-admin" and "wp-includes"
- Overwrite all files except "wp-content" with fresh copy of previous version,
- Open browser and visit your bolg, If no problem do the same with wp2.6.

I did this without touching anything in wp-config.php and database, and it is running now with no problem.

If you still get any problems, It must be a good ideas for a fresh install.

Here's step by steps to backup wordpress database:

Which plugin u used...
Most of the plugins will create backup files before upgradation so u are in safer side...
U just need to post ur problem to plugin forum or directly to plugin author...
i am sure the problem will be rectified
