Hi,
we are currently migrating the developed page to production and are getting following errors everywhere plugin is used:
Warning: sizeof(): Parameter must be an array or an object that implements Countable in \astra-child02\search-filter\2423.php on line 44
Warning: count(): Parameter must be an array or an object that implements Countable in \astra-child02\search-filter\2423.php on line 76
Warning: Invalid argument supplied for foreach() in \astra-child02\search-filter\2423.php on line 79
Warning: sizeof(): Parameter must be an array or an object that implements Countable in \astra-child02\search-filter\2423.php on line 44
… it goes on with changes of lines, but the error stays the same.
Can you advise us how to solve this issue?
Thank you for your help,
Sasha
