Yes, all OK. I'ts my fault, the function func_search_products was changed in 4.1.9.
There is less quality decision than previous. Please rollback changes and choose standart bestsellers.php file (without modifications). Then you should insert this code into bestsellers.php
Code:
foreach ($bestsellers as $k => $v) {
$bestsellers[$k]['descr'] = func_query_first_cell("select descr from $sql_tbl[products] where productid='$v[productid]'");
}
before lines (almost the end of file)
Code:
$smarty->assign("bestsellers", $bestsellers);
?>
I've tested this on 4.1.8 and found this work properly.
Feel free to ask any questions.
