Mad_Griffith:
I've just done that, but still no luck. I think the problem is in the SQL command I inserted in Admin > Tools > Install Patch SQL. How do I "delete" it? Here is the original command specified in the readme file that comes with Column Layout Grid mod:
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'),');
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 - Columns Per Row', 'PRODUCT_LISTING_COLUMNS_PER_ROW', '3',
'Select the number of columns of products to show in each row in the product listing.
The default setting is 3.', '8', '41', NULL, now(), NULL, NULL);
I doubt that caused any problems with adding products; I can't see how. It goes NOWHERE near the product adding code. Either way, I personally am no good with SQL queries, I always to to phpmyadmin and delete things manually.
What else have you changed recently?
