I have a wordpress site and after importing the needed database to my site I get the following error after posting or editing a post : WordPress database error: [Table '*****_*****.wp_post2cat' doesn't exist] SELECT cat_ID AS ID, MAX(post_modified) AS last_mod FROM `wp_posts` p LEFT JOIN `wp_post2cat` pc ON p.ID = pc.post_id LEFT JOIN `wp_categories` c ON pc.category_id = c.cat_ID WHERE post_status = 'publish' GROUP BY cat_ID WordPress database error: [Table '*****_*****.wp_post2cat' doesn't exist] SELECT cat_ID AS ID, MAX(post_modified) AS last_mod FROM `wp_posts` p LEFT JOIN `wp_post2cat` pc ON p.ID = pc.post_id LEFT JOIN `wp_categories` c ON pc.category_id = c.cat_ID WHERE post_status = 'publish' GROUP BY cat_ID Warning: Cannot modify header information - headers already sent by (output started at /home/*****/public_html/******/wp-includes/wp-db.php:160) in /home/*****/public_html/******/wp-includes/pluggable.php on line 390 that was my first problem. The second one is that when I try to activate some plugins like statspress and wp-usersonline , they get activated but don't work properly. If u think u can fix these problems then please post here or pm me.
The problem is that some of your plugins do not support the new 2.3 WP version. 2.3 removes those category and do not use them anymore. In conclusion, your plugin is not compatible with 2.3. A common problem, you dont have to pay for people to help you.
I'm stunned. I just came in to post the exact same error that i have with two of my blogs. Ill be checking your tips.
I can not believe this…. Pfff. I was working on those errors and I completed the list with tips that amitpatel_3001 suggested with his link but nothing worked. Last thing I did was disable all the plugins one by one and checked if I still had the same error. About a month ago I upgraded 4 blogs at the same time. All four are practically identical with the same themes and plugins. I upgraded to WP2.3 and I also upgraded all the plugins with a list where I written down all the plugins versions numbers. But now it seems that while I was upgrading the plugins for these four blogs I missed two blogs for some kind of reason. Two blogs (the ones that gave me the error) had an older version of the google sitemap plugin. This is really unbelievable; it was 5 am last night when I went to bed. Unbelievable…. I’m glad though that the blogs are working now without any errors. Thanks guys for the tips!!
ah, glad you wer able to fix your problems....I have not upgraded mine yet. I plan to wait till there is a good stable version....hopefull in a month or so...
