“wp_categories’ doesn’t exist” error in database wp 2.3

You running plugins that might query THAT table? As Ryan Boren stated: “The big schema change is the dropping of the categories, post2cat, and link2cat changes in favor of the new terms, term_taxonomy, and term_relationship tables. Any plugin that queries against the old table will break horribly.”

These three tables were dropped after/during your upgrade: categories, post2cat, and link2cat. Please disable any plugins that might be using one of those three older tables, and try again. You can look here to see if your plugins were updated for 2.3 or not. Thanks.

Also, like said on Upgrade instructions.. PLUGINS SHOULD BE DISABLED BEFORE UPGRADING BLOGS!

I had all the plugins deactivated to update wordpress and now in my test blog I am not using none plugin and the problem is there.

I have tried to do a test, to install the version 2.13, update, all fine then, but after install the 2.3 version again the same error.

I have this error in my k2 comfiguration section

Perhaps K2 itself is the culprit? I’m not familiar with K2 at all, did they announce any possible up-to-date versions of K2 lately, that may work on 2.3 version? As I said, I’m not familiar with K2 at all really… so I wouldn’t know. Maybe someone else in here will know? Good luck. =)

Ok i go to try install a k2 new template for test.

I’ve run into the same problem with those plugins (recent posts and category exclusion) that rely on the old category schema. Does anyone have any idea how the new structure can be queried to achieve the same aim? For example, what kind of query would one need to pull recent posts from the database? Thanks.

Finally seems was k2 template problem, i removed this lines in the configuration and now seems work fine:

// Get the asides category
	$asides_id = get_option('k2asidescategory');
	$asides_title = $asides_id != 0 ? $wpdb->get_var("SELECT cat_name from $wpdb->categories WHERE cat_ID = $asides_id LIMIT 1") : __('No Asides','k2_domain');

	// Get the categories we might use for asides
	$asides_cats = $wpdb->get_results("SELECT cat_ID, cat_name FROM $wpdb->categories");

			<h3><?php _e('Asides','k2_domain'); ?></h3>

			<p><small><?php _e('\'Asides\' is a category of entries, meant to be \'smaller\' and perhaps of \'less importance\', like for instance links with minor commentary.

I found out that my Ultimate Tag Warrior plugin was the one generating these errors. I would import that plugins tags into the native tags area but where the hell are the importers? I can’t find them

I’m getting the same error using the Custom Query String UTW plug-in.

Hopefully the developers of these plug-ins will release updates for 2.3 soon. Its really appreciated.

I did four upgrades that had no problems on two different domains hosted by the same ISP. However two upgrades on a different domain hosted by a different ISP had this problem. This is a VERY serious problem as it is exposing the database structure. I hope it can get resolved quickly. Thanks.

my k2 based site is running.. i had some errors while upgrading using upgrade.php and the interface worked fine.. i imported the tags from UTW and disabled utw and similar post plugins along with few others…. now the error when i post something or try to delete the post.. it says things like

anyone has any idea on solving this issue?

Upon further thought about the problems on my installations. I wonder I successful upgrades from an incremental version while the unsuccessful upgrade was based on an much earlier version of wp (I don’t recall the delete tables command on the successful upgrade).

It seems like there are a lot of installation problem posts. Is there a way to safely DOWNGRADE to a more stable version that avoids this (and other problems)?

BTW minimalnet what file had the configuration you mentioned earlier?

Also, I don’t know what you mean when you are referring to “K2”

Thanks.

@americasroof – k2 is a well known simple manageable template which offers a bit more than the usual.. https://www.getk2.com..

have a look at the pictures.. after all the error while posting.. it actually post the entry.. ;]
