Database errors

Hi,

All seems to work fine apart from I get the following error in my WP error log:

[13-Jul-2014 16:18:05 UTC] WordPress database 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 ‘status timestamp <= 1310660285 and id not in (select redirect_id from obnw_wbz40’ at line 1 for query select id from obnw_wbz404_redirects where status = 2 status timestamp <= 1310660285 and id not in (select redirect_id from obnw_wbz404_logs) made by do_action_ref_array, call_user_func_array, wbz404_cleaningCron

Any idea what it is?

Regards
Keith
