Wordpress’ latest release 2.1. is a clear hi and bye for me.
Seems like it is not yet ready for launch.

The upgrade process this time was somewhat troublesome: if I didn’t mix up things WP 2.1 adds a table called link2cat to your database, which -prior to 2.1.- didn’t exist.

This change conflicted with various plugins I had used before, e.g. the Sideblog Wordpress Plugin by Kates. But hence I didn’t know what went wrong after upgrading I had to play blindfish for about an hour. Somehow the pages of my site disappeared. All wordpress pages were no longer accessible and returned a 404 error.
Weird, because on the Admin area they were still visible and editable.
Another page was accessible, but the next, or newly created pages weren’t.
After all I found out that this was caused by combination of changes.

a. wordpress 2.1
b. Sideblog Wordpress Plugin 3.6

in the process of switching back I ruined my database and had to reupload a backup.
I am lucky now I got all posts and pages back and working and will conclude by saying
“never change a running system”.

p.s. I will get the themes coming as soon as I got the right permissions on the themeviewer website by wordpress.
Two themes that are ready so far are called corporateFK and fastr. No it is not related to flickr or simplr, but thanks for asking!
