Hi Karina,

I've checked the functions that you identified in post #27 and in both the $sql_tbl array has been defined.

I've also added the require get_language.php mod that you have prescribed and still get the SQL error if the interval is set for 9 days, but I know this change was required for the subject line fault, which I had noticed in customers' emails that had been rejected by their mail service and bounced back to me.

Just an observation: Running send_review_reminders.php with the above mod found 487 emails to send that were not found yesterday!! Would you have expected this or should I take a closer look at my SQL problem?
