Upgrading to 2.3 - what went wrong and how I fixed it

So I’ve upgraded to WordPress 2.3 and it wasn’t completely smooth but wasn’t too hard either - although there’s been a few tweaks and a couple of plug-ins don’t work yet.

Here’s what I did:

1. Backed up using mySql then discovered I had Wordpress Backup plugin so backed up with that as well.
2. Deactivated Sidebar widgets and got:Fatal error: Call to undefined function: register_sidebar_widget() in /home/users/web/b2996/ipw.redsulta/public_html/WordPress/wp-content/plugins/widgets.1.0/nrs_fold_pages.php on line 118Grrrr.
3. Deleted Widgets 1.0 FTP.
4. Downloaded 2.3 upgrade files from http://wordpress.org/download/
5. Hmmm new folder is wordpress, old folder is Wordpress… do I change the name?
6. Try not changing name first…
7. Hmmm it didn’t like that… created a new folder rather than overwriting…
8. Okay try overwriting files into Wordpress…
9. Upgrade complete but I get this error:Warning: array_key_exists(): The first argument should be either a string or an integer in /home/users/web/b2996/ipw.redsulta/public_html/WordPress/wp-includes/category-template.php on line 176
10. It’s something to do with the theme. I change from Misty Look to Kubrick and it’s fine. But it’s not my preferred theme.
11. Look for new compatible theme… download Mandigo - http://www.onehertz.com/portfolio/wordpress/mandigo/testrun/
12. Find this code at Nathan Rice - http://www.nathanrice.net/blog/wordpress-23-theme-backward-compatibility/ but can’t seem to make this work so giving up on Misty Look theme and instead start searching for another theme to customise!
13. Ahhh Meg finds me the link to the new version of Misty Look… http://mistylook.org/
14. But stupidly I overwrite my style page and now my random header doesn’t work. Arghhh. Also half my old sidebar bits are missing…
15. I’m over Misty Look anyway! So find new theme here.
16. Have dinner party with friends and have a great time.
17. Start re-activating plug-ins, updating when they either don’t work or have a little “this plug-in has been updated” note.
18. The Silas Partners plug-in that used to display my flickr photos has spat itself.
19. Start “Sultana-ising” Beauty-50… by changing the images and the font colours.
20. Update this blog and start worrying about my photo plug-in.
21. It’s 4.02am. Must go to bed.
22. Found fix for error in photo plug-in but still does not have the ability to drag photos into posts.
