Enfold portfolio grid with Polylang

Hello,

I’m using Enfold theme with Polylang and am having trouble with one function of the Portfolio Grid.

I’ve set the portfolio grid to show a maximum of 16 items. When there are more than 16 items, a page selector (1,2,3) becomes available at the bottom of the grid. When the user clicks on ‘2’ for example, they are redirected to an error page that says:
“Nothing Found. Sorry, the post you are looking for is not available. Maybe you want to perform a search?”

Are you able to help me with this problem?

I’m not sure if this would affect the functionality, but I have used some custom code found on the forum so that Ajax search would only search in the current language:

/**
 * Ajax Search Query
 */
 
add_filter('avf_ajax_search_query', 'avf_modify_ajax_search_query', 10, 1);
function avf_modify_ajax_search_query($search_parameters)
{
$language = pll_current_language();
parse_str($search_parameters, $params);
$params['lang'] = $language;
$search_parameters = http_build_query($params);
return $search_parameters;
}

Thanks!
