The database table for Contact Form 7 does not exist

You might have a table (prefix)_contact_form_7 on your database. If so, drop the table and try reactivation of the plugin.

If not, please tell me your environments in detail.

I have the same issue.
Im using the latest CF7 and WP 2.8.6

When I click on create the table, nothing happens, the same page reloads, and a “tanbl_not_created” appears in browser address.

It’s the first time I use CF7 (I was using cforms before), and I wonder if it’s a plugin bug?

Thanks for your help!

Same issue: WordPress 3.0, PHP Version 5.2.9, MySQL server version 4.1.20

Manually creating the table worked for me. I hope this helps others in the same predicament:

CREATE TABLE IF NOT EXISTS <your_wp_db_prefix>_contact_form_7 (
cf7_unit_id bigint(20) unsigned NOT NULL auto_increment,
title varchar(200) NOT NULL default '',
form text NOT NULL,
mail text NOT NULL,
mail_2 text NOT NULL,
messages text NOT NULL,
additional_settings text NOT NULL,
PRIMARY KEY (cf7_unit_id));
