With the release of a new major version of WordPress, there are bound to be issues with themes and plugins out in the wild. I suppose that’s why the core team recommends updating themes and plugins throughout the development process each and every time WordPress is in RC.
As you venture forward with WordPress 3.3, or consider doing so this week, you might want to know just what to keep an eye out for when you upgrade. To put your mind at ease we’ve collected every instance of plugin compatibility issues and developer footnotes that you could want to know about when upgrading.
Keep in mind that many of these are small issues which shouldn’t keep you from upgrading. Go. Upgrade. Now. But just know that you might see some of the below happening while plugins and themes get their 3.3 act together.
Plugin conflicts/errors with 3.3
These are the plugins we know of that are currently causing conflicts with WordPress 3.3:
- The Postie plugin is reportedly causing conflicts that while “white screen” or keep you from getting to your Dashboard. Disable before upgrading.
- qTranslate has not yet been tested for 3.3 yet, and will disable itself upon activation (via comments).
- The Organize Series plugin seems to include a few minor incompatibilities right now, though Darren says he will have them cleaned up by the week’s end.
- It seems the Markdown QuickTags plugin breaks upon upgrade to 3.3.
Tip: Developers should use
This one’s a best practice that’s been around for a while, but core developer Andrew Nacin reminded everyone on the WordPress developer’s blog today since not doing so will cause a small issue with 3.3:
A possible incompatibility with WordPress 3.3 could arise if you are using the wp_print_styles hook to enqueue styles — your styles may end up in the admin.
The fix: Use wp_enqueue_scripts instead. Yes, it’s that easy.
So if you enqueue styles in your theme or plugin, be sure to update it to use
wp_enqueue_scripts so you don’t muck up styles on the Dashboard.
BuddyPress is due for a maintenance update
There’s no threat of your site falling over with this one, but know that when you upgrade (and until BuddyPress 1.5.2 is out in the next day or two) there might be repeated items in your toolbar or some extra padding on the left margins of the Dashboard.
You can read more about this one on the BuddyPress forums.
Login Logo update includes a CSS fix
WP Engine recommends against upgrading for now
For their customers, and due to issues they’ve discovered, WP Engine is recommending against upgrading at this point.
That does it for issues we’ve seen popping up so far. We’ll keep this post updated as we hear of anything else. If you run across an issue somewhere, be sure to notify the plugin or theme’s developer, and comment below so we can keep everyone updated.
