How to make the export-import module work correctly on a new site?

Question

opencart

Good afternoon. There was a question about this export-import module on the new site. https://opencartforum.com/topic/58024-podderzhka-e... I added products through the module and set categories for them, they are displayed via a direct link on the site. Example: http://gamma24.rf/index.php?route=product/product&... But at the same time they are not displayed in the category and are not found through the search! They appear in the category only if you go to the card of this product through the admin panel and click save. What could be the reason?
Additionally : I will say that I use this module on other sites and this question did not even arise...

Answer 1

there was a reason in the Brainy Filter, it was necessary to update the cache of this filter and everything worked

Answer 2

most likely you have some data not entered into one of the tables, as a result, when they are combined, there is no record of the product and, as a result, it is not on the storefront
if the tables in the database were corrected, then modify the import/export
