Hi, I'm still getting a blank page in zencart Admin - Configuration - Configure RCS and would be really grateful for your help.

This is what I've got:
Zen Cart 1.5.1
Recover Cart Sales - Version: 4.00.00a
PHP Version: 5.2.17
Database: MySQL 5.0.77

I made the changes you suggested in post no. 541 of this thread, deleted the configuration_group table entry associated with the name "Recover Cart Sales", made sure that there are no items in the configuration table that start with RCS_ and then re-ran the SQL that you posted in post no. 548.

I don't get any error messages, just keep getting a blank at Admin - Configuration - Configure RCS.

Thank you!
