In short order the upgrade to WordPress 2.1 was a tad more complicated than expected.
I followed the instructions for upgrading exactly. My upgrades tend to fail on the last step – running the upgrade.php. The called for database updates fail completely.
The blog was back and operational, but there were errors. I printed out the errors generated from upgrade.php and did the updates to the database manually using phpMyAdmin. It was a little slow going, but I have enough of a background so that the SQL statements were not insurmountable. Of course I had to dabble while I was in there, and I took the opportunity to delete tables leftover from old plugins.
Everything else appeared to work fine, but my blogroll (links) were a mess. Most did not get labeled (categorized) so I had to do that manually. Once that was done the blogroll was duplicated, with all the links in their respective categories AND in the whichever category was listed first, effectively doubling the links. I tried all sorts of strategies, read the codex, and a bunch of posted help topics. All I could find was info on the php coding changes necessary to display links. Since I use widgets I looked through the links code in the widgets plugin. The code looked fine (hey, what do I know anyway…). I tried toggling various other plugins to no avail.
I got the idea that it was the way the theme (I’ve been using WP-Andreas01 1.3) was handling the links. I really didn’t want to change themes, mostly because of the work I have to do to reset widget order and the back-end coding I’ll have to do to fix my database pages, but I figured I’d invested about 4 hours already so I went ahead.
I had a nice Web 2.0 style theme, Subtle by Glued Ideas. I selected it and everything looked peachy.
In retrospect it was a great experience. I think the blog looks far better under the new theme, less choppy.
