Unless you've made other changes to EP, I would suggest starting over with a new version of easypopulate.php.
Starting at line 2052 you should have this code:
// already in the description, let's just update it
$sql =
"UPDATE ".TABLE_PRODUCTS_DESCRIPTION." SET
products_name='" . zen_db_input($name) . "',
products_description='" . zen_db_input($v_products_description[$key]) . "',
";
if ($ep_supported_mods['psd'] == true) {
$sql .= "
products_short_desc='" . zen_db_input($v_products_short_desc[$key]) . "',
";
}
$sql .= "
products_url='" . zen_db_input($v_products_url[$key]) . "'
WHERE
products_id = '$v_products_id' AND
language_id = '$key'";
Put a // in front of each of these lines. That's it!
This section of code normally would update the description file IF the description exists. This change means the description would never change through EP.
New items are added with an INSERT several lines above, so that does not change.
As always, check carefully and TEST, TEST, TEST. I did not actually try this, but the code says it all and I see no reason why it should not work.
