WordPress 2.3 Plugin Compatibility

WordPress 2.3 is gonna be released pretty soon but before you get all excited, there’s something you might want to know before you upgrade your WordPress installation. If you aren’t aware of it yet, this version has some plugin compatibility issues due to some schema changes that can result in breaking the plugins that you’re currently using.

WP 2.3 changes the database schema in 3 ways but the one with the biggest impact are the taxonomy related changes. What happened is that the development team decided to drop the categories, post2cat, and link2cat tables. This means that any plugin that use or require these tables will break.

In my case, there’s one particular plugin I’m using which is really important to my blog and is affected by this issue: the UTW or Ultimate Tag Warrior plugin. I hope the author would find a way to fix the problem or that the WordPress development team would make it easy for UTW users to import tags used by the plugin into the WordPress tagging system.

The WordPress community has started a list to help users and plugin authors to identify which plugins are working/compatible with WordPress 2.3 and which ones don’t or needs updating. To find out the compatibility of your current plugins, check out the WordPress 2.3 plugin compatibility list.

Btw, those of you who have been testing WordPress 2.3 Beta, you are encouraged to add to the plugins that you’re using and categorize them whether they work or needs work.

  1. re new themes – thank you. derived from fluidity ang dalawa doon. anyways, i am so buba talaga. nakalimutan kong may import option ang wordpress :mad: i moved my old installation na to the current one. so ngayon ay wala ng nasayang na post and comments. i was able to merge it!!! yuhooo.

  2. @Beng – Really? That sucks! Sayang naman yon mga old posts & comments mo. Do you have database backups? If you do, did you try to restore it using your backup?

    Btw, I just saw your recent theme releases. They all look good. Great job! :D

  3. don’t know what really happened. i was too busy with my studies that time kaya hindi ko ito talaga napagtunan ng pansin. fact is, that several post and comments got messed up. wala na ang mga ito sa tamang category. i can’t figure out what caused the problem, but i really don’t care about it anymore. ginawa ko nalang Kauderwelsch Archive ang lumang installation.

  4. @jhay – Yup, it’s that time again. But now, I’m not that worried anymore coz I know that WP 2.3 has a built-in importer for UTW tags.

    I forgot to mention another plugin I’m using that’s affected by the tagging issue: Extended Live Archives. I’ve already found a fix but haven’t tried it yet. Will try it out as soon as WP 2.3 is released. Something to look forward to and play with. Hehe :)

  5. @trench – Scared? Don’t be! I also love my plugins but I’m sure it won’t be long until the authors update them.

    Btw, which plugins are you using that’s not compatible with WP 2.3?

  6. oh my goat! why do they keep on changing something everytime they make an upgrade. nope don’t answer this silly question of mine Jaypee :wink:

    i am luckily not using a plugin which is using queries to those tables you mentioned. i am bit careful at the moment due to my update experience to version 2.2 series. my site got messed up thus i decided to install my wp site in another database :cry:

  7. @Allen – Same here. I have another plugin that doesn’t work with 2.3, WP Useronline. You can look for alternative plugins but if I were you, just a while coz I’m sure most of the authors would update these plugins to work with 2.3. :)

  8. I’m quite excited on the release of wordpress 2.3. However, some of the plug ins I use have compatibility issues so I need to look for alternate plug ins first. haha ^_^

  9. @Joni – No it doesn’t. The tagging feature was supposed to be included in WP 2.2 but it didn’t make it on time for the release so it will be included in version 2.3.

    Btw, I think you got mixed up. What I’m talking about in this post is the coming WordPress 2.3 version and not 2.2.3. :)

  10. Hi Jaypee. Does version 2.2.3 have a built-in tagging feature similar to UTW? I can't find it in my dashboard. I must be searching in vain. Heh.

    Good thing my plugins weren't affected by the upgrade. :)
