Hi support, I had to deactivate your Woocommerce-Product-Filter plugin to get Wordpress working - Wordpress sent me the error:

WordPress version 6.8.2
Current theme: Taco Child (Final WPZOOM Fix) (version )
Current plugin: HUSKY - Products Filter Professional for WooCommerce (version 3.3.7.1)
PHP version 8.3.23

Error Details
=============
An error of type E_ERROR was caused in line 183 of the file /home3/iovvtcmy/public_html/wp-content/plugins/woocommerce-products-filter-OFF/index.php. Error message: Uncaught TypeError: Cannot access offset of type string on string in /home3/iovvtcmy/public_html/wp-content/plugins/woocommerce-products-filter/index.php:183

thrown

Your index.php file around this line 183 is as follows:

//***
if (!isset($this->settings) || !is_array($this->settings)) {
$this->settings = [];
}
$this->settings['delete_image'] = apply_filters('woof_delete_img_url', WOOF_LINK ."img/delete.png");

load_plugin_textdomain('woocommerce-products-filter', false, dirname(plugin_basename(__FILE__)) . '/languages');
add_filter('plugin_action_links_' . WOOF_PLUGIN_NAME, array($this, 'plugin_action_links'), 50);
add_action('woocommerce_settings_tabs_array', array($this, 'woocommerce_settings_tabs_array'), 50);
add_action('woocommerce_settings_tabs_woof', array($this, 'print_plugin_options'), 50);

 

Please advise how to fix?? What happens if I download & reinstall the plugin? Will I loose my existing settings that this plugin provides on my Website.

Thanks
