I am getting a lot of errors like this in my debug file:
[23-Jan-2017 01:11:20 UTC] WordPress database error Table 'skizzar_db.wp_subscriptions_log_table' doesn't exist for query SELECT id FROM wp_subscriptions_log_table WHERE mail_date < 1482455480 made by require_once('wp-load.php'), require_once('wp-config.php'), require_once('wp-settings.php'), do_action('init'), WP_Hook->do_action, WP_Hook->apply_filters, call_user_func_array, Incsub_Subscribe_By_Email->maybe_delete_logs, incsub_sbe_get_campaigns_since
Seems to be related to the subscribe by email plugin. I've checked my database and there is no wp_subscriptions_log_table - I don't mind creating this manually if you can tell me the settings for each column that I need. Or if there is an alternative way to resolve this issue.
