FYI- SQL syntax error

I know you told me Advanced Visit Counter is not yet optimized for multisites, but so you know…in testing it it throws this error:

[26-Jun-2020 15:44:03 UTC] Error You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘ORDER BY last_date DESC’ at line 1 de la base de datos de WordPress para la consulta SELECT last_date FROM ANYsite_6_avc_page_visit_history WHERE ip_address=’00.249.66.204′ AND article_id= ORDER BY last_date DESC realizada por require(‘wp-blog-header.php’), wp, WP->main, do_action_ref_array(‘wp’), WP_Hook->do_action, WP_Hook->apply_filters, Advanced_Visit_Counter_Public->update_page_visit_stats

Thanks!
