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, pl.pl_title AS sel_title, pl.pl_namespace AS sel_ns, `page`.page_title as sortkey FROM `pagelinks` AS pl, `page` WHERE 1=1 AND (`page`.page_title REGEXP 'RU/kb/[0-9]') AND `page`.page_is_redirect=0 AND `page`.page_id=pl.pl_from AND ( (pl.pl_namespace=2 AND pl.pl_title LIKE 'Sancho/test/childs')) ORDER BY page_title ASC LIMIT 0, 500

Error message is:
Character set 'utf8mb3_bin' cannot be used in conjunction with 'binary' in call to regexp_like. (127.0.0.1)
