Categories and sub-categories “Warning: sizeof()”
-
Hey I’m working on a wordpress site and I activated the Ultimate Product Catalog.
When I started working with the catalog everything was alright, now I added some products, categories and sub-categories and no products show up on the catalog page, just this 2 errors:
Warning: sizeof(): Parameter must be an array or an object that implements Countable in C:\xampp\htdocs\wordpress-inventario-otbox\wp-content\plugins\ultimate-product-catalogue\Functions\Shortcodes.php on line 1826
Warning: sizeof(): Parameter must be an array or an object that implements Countable in C:\xampp\htdocs\wordpress-inventario-otbox\wp-content\plugins\ultimate-product-catalogue\Functions\Shortcodes.php on line 1897
I went to check, and they are about the categories and sub-categories, here are only those lines:
line 1825 and 1826
// Create the categories checkboxes
if ($Sidebar_Item == “Categories” and sizeof($Categories) > 0) {
//line 1896 and 1897
// Create the sub-categories checkboxes
if ($Sidebar_Item == “Sub-Categories” and sizeof($SubCategories) > 0 and $Sidebar_Order != “Hierarchical”) {
//How can I solve this problem?
Edit: the php version is 7.3.5
