I spent most of my Friday upgrading WordPress installations (this blog, my Golf blog, the FeedLounge site and the King Design site). For the most part, everything went smoothly – however there were a few notable exceptions.
I was upgrading all of these sites from 1.5.2 (plus security patches) except for the Golf blog. I had no trouble to speak of upgrading this blog or the golf blog; then I got to the FeedLounge site.
- I ran into some caching issues right away on the test server and had to disable cache.
- The upgrade plus the cache issue also seemed to convert me back to the old FeedLounge theme – possibly due to the theme name having a space in it (“FeedLounge v2″ vs. “FeedLounge”).
- The changes in how the rewrite rules are handled violently disagreed with the permalink structure I’d chosen for feedlounge.com. The main problem was me wanting /blog to be both the root of the blog and the base for the categories. I was finally able to track down the specific problem and fix it – more on this later.
- Then feedlounge.com went away for a bit. Good times!
The King Design site was pretty smooth, with the only issues being:
get_the_excerpt()no longer appears to work for pages.
- The new rewrite rule handling broke some of my
For being such a major upgrade, I have to say WordPress did a pretty good job keeping things compatible. With a project used in such a wide variety of ways, it must be a huge challenge to keep moving forward while trying not to break existing installations.
I plan to report the issues I ran into1 with test cases so that folks can decide if they are worth fixing or not. Details of the issues and work-arounds to follow when I have more time.
UPDATE: Oops, found one other issue. It seems that WP now loads the execute-pings.php page via an internal GET call (in the
spawn_pinger() function). If you’ve password protected your /wp-admin directory (as I think is a wise idea), sending pings and trackbacks will not happen unless you manually load the execute-pings.php page. I’ll try fixing this via plugin if I can.
- Actually, I’ve reported some already. [back]
