    I have this error:

    ———–
    WordPress database error: [Duplicate entry ‘0’ for key 1]
    INSERT INTO wp_post2cat (post_id, category_id) VALUES (’68’, ‘1’)

    WordPress database error: [Duplicate entry ‘0’ for key 1]
    INSERT INTO wp_postmeta (post_id,meta_key,meta_value) VALUES (’68’,’_wp_page_template’,’default’)

    Warning: Cannot modify header information – headers already sent by (output started at /home/lemonlan/public_html/wp-includes/wp-db.php:133) in /home/lemonlan/public_html/wp-includes/pluggable.php on line 331

    I’ve done this:
    http://wordpress.org/support/topic/107994

    and this:
    http://wordpress.org/support/topic/129725

    and deactivated all of my plugins.

    This problem showed up after I moved to a new server.

    Make sure your database tables are correctly defined. Use phpMyAdmin and look at the structure of your tables and make sure they agree with [[Database_Description/2.2]].

    In particular, make sure the tables with auto increment reflect that in your database tables.

    I’ve noticed that my old Information_schema had 16 tables.

    My new Infomation_schema has 17, the new one being “profiling”. Is that the problem? If so, what should I do?

    profiling isn’t a table that is part of the WordPress core tables. Maybe from a plugin.

    I am in phpmyadmin, but I am unsure how to know if my tables “agree” with database_description/2.2. Where is that found?

    Problem solved! I uploaded my backup .sql file and linked the config.php file to the new database and now it works!

    Thank you for your help Michael!
