'service Is Temporarily Unavailable' Error Deleting Categories

Hi,



I’m running Multi-vendor 4.3.1 and every time I delete a default Category I receive the Error message: “Sorry, service is temporarily unavailable”.



When I enable the Debug Mode, it says:



Message

Column ‘path’ cannot be null (1048)

INSERT INTO cscart_seo_names (name, type, object_id, dispatch, lang_code, path) VALUES (‘john-rutter-the-colours-of-christmas’, ‘p’, 200, ‘’, ‘en’, NULL) ON DUPLICATE KEY UPDATE name = ‘john-rutter-the-colours-of-christmas’, type = ‘p’, object_id = 200, dispatch = ‘’, lang_code = ‘en’, path = NULL



Error at

app/Tygh/Database.php, line: 677













*** app/Tygh/Database.php CODE ***



671 // Log database errors

672 fn_log_event(‘database’, ‘error’, array(

673 ‘error’ => $error,

674 ‘backtrace’ => debug_backtrace()

675 ));

676

677 throw new DatabaseException($error[‘message’] . “

{$error[‘query’]}

”);

678 }

679 }

680

681 return false;

682 }

****



When I go back to the Admin console, the category has been removed thought.





Any idea how to troubleshoot this? Does it have a side effect the fact that we get an error message but the category is deleted?



Many thanks
