Thanks. Disabling Woocommerce Catalog Enquiry plug-in helped!
In my opinion you can resolve this ticket.
Updated to 4.1.6, refreshed site. Price filter does not work. Do I need te reinstall plug-in?
I don’t have a custom field and nor do I have an active sidebar. After updating, the price filter still does not work. Do I need to reinstall plug-in?
In shortcodes.php, I temporarly deleted the following lines 1381/1382.
foreach ($Sidebar_Counts[‘Custom Fields’] as $Field_ID => $Values) {$Fields_String .= $Field_ID . “,”;}
$Fields_String = trim($Fields_String, “,”);
Error message is gone, but the price slider doesn’t work anymore. Not perfect, but a temp workaround.
