Database Problems

Making some changes in the admin and some work fine, however on many i’m getting a database error.

for example, when trying to add a category i’m getting the following.

Database error: Incorrect integer value: ‘’ for column ‘product_columns’ at row 1 (1366)

Invalid query: INSERT INTO cscart_categories (parent_id, status, usergroup_ids, position, timestamp, age_verification, age_limit, default_layout, selected_layouts, product_columns) VALUES (‘0’, ‘A’, ‘0’, ‘10’, ‘1264204800’, ‘N’, ‘0’, ‘’, ‘’, ‘’)
