Erro Invalid column name 'RowNumber'

Olá galera, estou com um problema quando estava criando um novo site.
Tenho no meu index os campos:

<div id="col580">
<div id="main">
<jdoc:include type="message" />
<jdoc:include type="component" />
</div><!-- end main -->
</div><!-- end main -->

E quando coloquei e fiz um artigo após atualizar o joomla pela administração mesmo.
Olha o que aparece na página do site (frontend):

[Microsoft][SQL Server Native Client 11.0][SQL Server]Invalid column name 'RowNumber'.SQL=SELECT TOP 9 * FROM (SELECT a.id, a.title, a.alias, a.title_alias, a.introtext, a.checked_out, a.checked_out_time, a.catid, a.created, a.created_by, a.created_by_alias, CASE WHEN a.modified = 0 THEN a.created ELSE a.modified END as modified, a.modified_by, uam.name as modified_by_name,CASE WHEN a.publish_up = 0 THEN a.created ELSE a.publish_up END as publish_up,a.publish_down, a.images, a.urls, a.attribs, a.metadata, a.metakey, a.metadesc, a.access, a.hits, a.xreference, a.featured, LEN(a.fulltext) AS readmore,CASE WHEN badcats.id is not null THEN 0 ELSE a.state END AS state,c.title AS category_title, c.path AS category_route, c.access AS category_access, c.alias AS category_alias,CASE WHEN a.created_by_alias > ' ' THEN a.created_by_alias ELSE ua.name END AS author,ua.email AS author_email,( SELECT MAX(contact.id) AS id ,ROW_NUMBER() OVER (ORDER BY c.lft, CASE WHEN a.publish_up = 0 THEN a.created ELSE a.publish_up END DESC , a.created DESC) AS RowNumber FROM jos_contact_details AS contact WHERE contact.published = 1 AND contact.user_id = a.created_by AND (contact.language in (N'pt-BR',N'*') OR contact.language IS NULL)) as contactid,parent.title as parent_title, parent.id as parent_id, parent.path as parent_route, parent.alias as parent_alias,ROUND(v.rating_sum / v.rating_count, 0) AS rating, v.rating_count as rating_count,c.published, CASE WHEN badcats.id is null THEN c.published ELSE 0 END AS parents_published FROM jos_content AS a LEFT JOIN jos_categories AS c ON c.id = a.catid LEFT JOIN jos_users AS ua ON ua.id = a.created_by LEFT JOIN jos_users AS uam ON uam.id = a.modified_by LEFT JOIN jos_categories as parent ON parent.id = c.parent_id LEFT JOIN jos_content_rating AS v ON a.id = v.content_id LEFT OUTER JOIN (SELECT cat.id as id FROM jos_categories AS cat JOIN jos_categories AS parent ON cat.lft BETWEEN parent.lft AND parent.rgt WHERE parent.extension = N'com_content' AND parent.published != 1 GROUP BY cat.id ) AS badcats ON badcats.id = c.id INNER JOIN jos_content_frontpage AS fp ON fp.content_id = a.id WHERE a.access IN (1,1) AND c.access IN (1,1) AND CASE WHEN badcats.id is null THEN a.state ELSE 0 END = 1 AND (a.publish_up = N'1900-01-01 00:00:00' OR a.publish_up <= N'2013-11-05 19:44:42') AND (a.publish_down = N'1900-01-01 00:00:00' OR a.publish_down >= N'2013-11-05 19:44:42') AND a.language in (N'pt-BR',N'*') ) _myResults WHERE RowNumber > 0


Alguém tem alguma ideia de como proceder para consertar isso?
