Plugin doesn’t send emails // sms

Hello,

bought plugin yesterday, set it up (email templates, rules for sending emails – 1 minute / 24 hours / 38 hours/ // sms – connected with twilio and bit.ly) and have problem now that the plugin doesn’t send emails or templates.

It did work for short time yesterday (got first part of email sequence) but doesn’t now (I did some test shopping – leave in the second step of check out process).

Cron is running.

My programmer was testing that and found out this error:

Fatal error: Uncaught Error: Call to a member function date_i18n() on null in /home3/reihylmy/public_html/wp-content/plugins/woocommerce-abandoned-cart-recovery/includes/email/send-email-cron.php:204 Stack trace: #0 /home3/reihylmy/public_html/wp-content/plugins/woocommerce-abandoned-cart-recovery/includes/email/send-email-cron.php(97): WACVP\Inc\Email\Send_Email_Cron->email_content(Object(stdClass), ‘26785’) #1 /home3/reihylmy/public_html/wp-includes/class-wp-hook.php(287): WACVP\Inc\Email\Send_Email_Cron->send_reminder_mail(”) #2 /home3/reihylmy/public_html/wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters(”, Array) #3 /home3/reihylmy/public_html/wp-includes/plugin.php(478): WP_Hook->do_action(Array) #4 /home3/reihylmy/public_html/wp-content/plugins/woocommerce-abandoned-cart-recovery/includes/cron.php(58): do_action(‘wacv_cron_send_…’) #5 /home3/reihylmy/public_html/wp-includes/class-wp-hook.php(287): WACVP\Inc\Cron->wacv_execute_cron() #6 /home3/reihylmy/public_html/wp-includes/class-wp-hook.php(311): WP_ in /home3/reihylmy/public_html/wp-content/plugins/woocommerce-abandoned-cart-recovery/includes/email/send-email-cron.php on line 204

Please, any idea how to fix this?

Thanks,
