Hi,
thank you. This update almost solves the issue. The filter module is now showing again on the hompage. The only problem that happens now is that I get a warning message when I perfom a search like this one:
Warning: count(): Parameter must be an array or an object that implements Countable in /home/xxxxxxxxxx/public_html/templates/gantry/html/com_k2/k2 template/category.php on line 264
Do you have a solution for that?
