I disabled a custom plugin with code that I think I got from Customizr site’s snippet section that was needed back then called Polylang Customizr, and the slider started working again. Problem sorted.
<?php
/*
Plugin Name: Polylang Customizr
Description: Makes Customizr frontpage multilingual with Polylang
License: GPLv3
*/
if (defined('POLYLANG_VERSION'))
add_filter('option_tc_theme_options', 'pll_tc_options');
function pll_tc_options($options) {
$areas = array('one', 'two', 'three');
if (is_admin()) {
pll_register_string('tc_featured_page_button_text', $options['tc_featured_page_button_text'], 'Customizr');
foreach ($areas as $area)
pll_register_string('tc_featured_text_'.$area, $options['tc_featured_text_'.$area], 'Customizr', true);
}
else {
$options['tc_featured_page_button_text'] = pll__($options['tc_featured_page_button_text']);
foreach ($areas as $area) {
$options['tc_featured_text_'.$area] = pll__($options['tc_featured_text_'.$area]);
$options['tc_featured_page_'.$area] = pll_get_post($options['tc_featured_page_'.$area]);
}
// filters sliders by language
$pll_options = get_option('polylang');
if (!empty($options['tc_sliders']) && $pll_options['media_support']) {
foreach ($options['tc_sliders'] as $slider => $images)
foreach ($images as $key => $img)
if (!(($id = pll_get_post($img)) && $id == $img))
unset($options['tc_sliders'][$slider][$key]);
}
}
return $options;
}
