The extension can't delete pages in mediawiki 1.35. I made clean installation of mw 1.35, but the extension produced this mistake:
[X6e-iHdCgXPzhVfh0ggh7wAAAQ4] /index.php?title=0444-5&action=delete_page_permanently Wikimedia\Rdbms\DBQueryError from line 1699 of /home/huzhusjy/math1solutions.ru/includes/libs/rdbms/database/Database.php: A database query error has occurred. Did you forget to run your application's database schema updater after upgrading?
