Hello, I just upgraded from the old version or recover cart sales to the new version of recover cart sales version and I am using zen cart 1.3.7 and PHP Version 5.05 and MySQL Version 5.0.27 and I am getting the following error message:

Warning: strtotime() [function.strtotime]: Called with an empty time parameter. in /home/MYUSERNAME/public_html/admin/recover_cart_sales.php on line 381

Besides all the errors it appears that the program is working since under all the errors I see all the customers and their abandoned carts.

The error message goes away after I contact the customer, so the error only shows on uncontacted customers.

I hope someone can please help me.

Thank you.
