When I go there all I get is a blank page with the words title, value, action. When I installed the SQL file I did not get any errors. I have tried to uninstall the module by running the uninstall_cowoa.sql file in the admin and get an error - Warning: An error occurred, please refresh the page and try again. I tried installing COWOA again on a backup site and the same thing happened.

I don't know if this helps at all but I was in the process of installing Fast and Easy Checkout when I decided to switch to COWOA. I have deleted all of the Fast and Easy Checkout files and ran the uninstall SQL on that module which worked fine.

I've googled and searched the forums but can't seem to find an answer to this problem that has worked. Does anyone have any idea how to fix this or know what I'm doing wrong? Thanks a bunch!
I have struggled with the same issue. New install of Zen Cart 1.5.1 with COWOA 2.3. Previously installed template tb_sempre. The log shows

PHP Fatal error: 1062uplicate entry 'PRODUCT_LISTING_LAYOUT_STYLE' for key 'unq_config_key_zen' :: INSERT INTO configuration (configuration_title, configuration_key, configuration_value, configuration_description, configuration_group_id, sort_order, last_modified, date_added, use_function, set_function) VALUES ('Product Listing - Layout Style', 'PRODUCT_LISTING_LAYOUT_STYLE', 'rows', 'Select the layout style:<br />Each product can be listed in its own row (rows option) or products can be listed in multiple columns per row (columns option)', '8', '40', NULL, now(), NULL, 'zen_cfg_select_option(array("rows", "columns"),'); in /home/nutraex/www/shop/includes/classes/db/mysql/query_factory.php on line 120

Anyone know how to solve this?
