[TYPO3-english] metaext problems

[Olga Zhuravleva]

I install metaext and have some problems.

Database status:*Table error!*
Probably one or more required fields/tables are missing in the database!

Code warnings:
(developer-relevant)Some tables or fields are missing!

In ext_tables.sql line repeat 2 times:
tx_metaext_publisher varchar(80) DEFAULT '' NOT NULL,

No metadata on page properties

Root pages of my sites are shortcats. May I add metatags to shortcat page
using metaext?
