Error en Create Table

[yournightmare86]

Pues resulta que he tenido problemas con mi ordpress, y me he visto obligado a restaurar la base de datos. Hice un backup pero cual es mi sorpresa que me da error al tratar de crear una tabla:

Código:

CREATE TABLE b18_331576_wordpressbd_posts(
ID bigint( 20 ) unsigned NOT NULL AUTO_INCREMENT ,
post_author bigint( 20 ) DEFAULT '0' NOT NULL ,
post_date datetime DEFAULT '0000-00-00 00:00:00' NOT NULL ,
post_date_gmt datetime DEFAULT '0000-00-00 00:00:00' NOT NULL ,
post_content longtext NOT NULL ,
post_title text NOT NULL ,
post_category int( 4 ) DEFAULT '0' NOT NULL ,
post_excerpt text NOT NULL ,
post_status enum( 'publish', 'draft', 'private', 'static', 'object', 'attachment', 'inherit', 'future' ) DEFAULT 'publish' NOT NULL ,
comment_status enum( 'open', 'closed', 'registered_only' ) DEFAULT 'open' NOT NULL ,
ping_status enum( 'open', 'closed' ) DEFAULT 'open' NOT NULL ,
post_password varchar( 20 ) NOT NULL ,
post_name varchar( 200 ) NOT NULL ,
to_ping text NOT NULL ,
pinged text NOT NULL ,
post_modified datetime DEFAULT '0000-00-00 00:00:00' NOT NULL ,
post_modified_gmt datetime DEFAULT '0000-00-00 00:00:00' NOT NULL ,
post_content_filtered text NOT NULL ,
post_parent bigint( 20 ) DEFAULT '0' NOT NULL ,
guid varchar( 255 ) NOT NULL ,
menu_order int( 11 ) DEFAULT '0' NOT NULL ,
post_type varchar( 20 ) DEFAULT 'post' NOT NULL ,
post_mime_type varchar( 100 ) NOT NULL ,
comment_count bigint( 20 ) DEFAULT '0' NOT NULL ,
PRIMARY KEY ( ID ) ,
KEY post_name( post_name ) ,
KEY type_status_date( post_type, post_status, post_date, ID ) ,
KEY post_related( post_name, post_content )
);

El error es el siguiente:

Código:

 MySQL ha dicho: Documentación
#1170 - BLOB/TEXT column 'post_content' used in key specification without a key length

Alguién puede echarme una mano? Temo haberme cargado 89 posts de mi blog:S.

Gracias y saludos.
