Best Plugins recommended by WP Webhost

I’ve successfully upgraded my blog from old version WP 2.6.x to 2.8 today.  The following is the steps that i sorted out:

1. Log in “wp-admin” to disable all existing Plugins (Important step)
2. Backup the mySQL database
3. Rename the existing blog directory (Backup the source)
4. Recreate the blog directory & Install the new version WordPress (can be easily uses Cpanel Fantastico)
5. Rename the new “wp-content” directory
6. Replace it by Copy back the original “wp-content” directory from backup source
7. Restore/Import the mySQL database into the new DB (Normally Fantastico will auto create a new DB)
8. Browse “wp-admin”, the system will prompt to click a button for upgrading the blog DB
9. Log in “wp-admin” to check the contents & settings
10. Some older version Plugins might need to be remove or reinstall (Find the compatible version before activate)
11. Grant the write permission to the path:  wp-content/uploads/
12. Edit “wp-config.php” to delete “utf8” at DB_CHARSET  (To make the encoding loads well)

NOTE:  Always be reminded to keep a copy of full backup before make any changes.

I was shock in this morning when sudden see all categories of my wordpress are gone and disappeared from the blog. All posts listed as “uncategorized” and I can’t get them in any setting inside the admin control panel.

Luckily with the PhpMyAdmin, I managed to view them in MySQL database under the table “wp_term_taxonomy”.

Finally I found the mystery was due to the tmp directory full at the server, so immediately the problem resolved after I free up that diskspace.

I get this weird error when upload image from “Add media” at Wordpress post editor:

File is empty. Please upload something more substantial. This error could also be caused by uploads being disabled in your php.ini”

But after that auto resolved in the next day…
