I can import a CSV to "jos_virtuemart_products_en_gb" using phpMyAdmin, but products do not show up in Virtuemart admin or the shop. But when I create new products within Virtuemart the SQL tables update next to where my imported CSV products are.
What am I doing wrong?
You might want to try the extension CSV Improved.
