WordPress 2.9 Upgrade And Simple Tags Solution
As expected WordPress 2.9 have been released on December 18 and while this version is not a security release, it contains quite a few bug fixes as well as enhancements! Couple most notable features added to latest version are:
- Basic image editing capabilities – love it for quick edits!
- Ability to add video to WordPress blog post by simply specifying URL to the video instead of copying / pasting code. Support for most common services is included
I also like the new option to Auto-Optimize database by simply adding one line to your wp-config.php file and my partner and I are testing it right now to perhaps make it part of the next package release of Expert WordPress. There are quite a few more enhancements you should read about on official blog but right now I want to talk about solving a problem with one, very popular plugin – Simple Tags. Until author releases next version of plugin fully compatible with WordPress 2.9 – here is a work around for you…
Problem comes from hard coding within the plugin that checks version of the WordPress core and errors out simply because it doesn’t mention 2.9.
If you are planning to upgrade to WordPress 2.9 and you should and using Simple Tags plugin, simply follow these steps to make it compatible…
1. Navigate to Plugins-> Editor in your WordPress admin
2. In “Select plugin to edit” drop down option on right hand side select “Simple Tags” and click Select:

simple-tags.php file should open for editing by default
3. Find this line near the top of the file:
if ( strpos($wp_version, '2.7') !== false || strpos($wp_version, '2.8') !== false) {
And add to it 2.9 as a version option:
if ( strpos($wp_version, '2.7') !== false || strpos($wp_version, '2.8') !== false || strpos($wp_version, '2.9') !== false ) {
4. Save the file!
This is it! Now your plugin will not give you any problems!

Hi Alex,
I have updated my blogs after reading your posts about blog security previously and as I am learning I am installing all the plugins you are recommending.
Just tonight I installed the WP Super Cache plugin as I noticed my blog loading really slow and I read about the plugin on your site.
Thank you for being such an expert with wordpress. I have learned so much since following you over the last few months.
Kind Regards
Jacinta

I upgraded WP 2.9 as soon as it out which I don’t normally do because the last few upgrades have been as smooth as possible.
The one time I rush it my plugins need a tweak, murphys law.
Alex,
Not really a Simple tags related comment, but I have had many problems since this 2.9 upgrade.
Has anyone else noticed their scheduled posts “missing” the schedule? I found a fix here:http://www.semiologic.com/2009/12/21/wp-2-9-three-bugs-and-how-to-fix-them/
I hope future upgrades go smoother than this one.
Thanks Dwayne,
This is a known issue and developers addressed it in 2.9.1 which should be out shortly.
@Dwayne
I’ve not been using WordPress long, came in at 2.8.5 and upgraded to 2.8.6 for security update.
I did read a lot about the problems with the initial release of 2.8 and now 2.9!
Looks like all the first releases need real life testing to find all the problems.
Perhaps the answer is to leave the first release to the beta testers and jump in with the release which fixes all the bugs.
I don’t like the idea of searching the internet for all the fixes.

Hi Alex,
got this error messages
fatal error,,,,,wp-content/plugins/simple-tags/simple-tags.php on line 35
What going on ? anyone face this problem?
The new WP version is absolutely a big factor to save time. Since the new version offers multiple plugins that has the ability to meet almost all the WP users’ needs.

The shortcuts here are going to save me a lot of time as well as encourage me to take the time to experiment a bit more before finalizing designs.
I’ve not been using WordPress very long, and I did update for security purposes.
I was concerned about the bad press the package received initially.
I didn’t have the time to debug the first version.
