The DPL extension (version 2.3.0) produced a SQL statement which lead to a Database error.
The reason may be an internal error of DPL or an error which you made,
especially when using DPL options like titleregexp.
Query text is:
SELECT DISTINCT `page`.page_namespace AS page_namespace,`page`.page_title AS page_title,`page`.page_id AS page_id, `page`.page_title AS sortkey, `page`.page_counter AS page_counter FROM `page` INNER JOIN `categorylinks` AS cl0 ON `page`.page_id=cl0.cl_from AND (cl0.cl_to='Analysis' OR cl0.cl_to='Script' OR cl0.cl_to='Time_of_running') WHERE 1=1 AND `page`.page_namespace IN ('0') AND `page`.page_is_redirect=0 ORDER BY page_title ASC LIMIT 500 OFFSET 0
Error message is:
Unknown column 'page.page_counter' in 'field list' (mysql-n)
