Hi I have an error message that appears on my site, someone can help me : Warning: array_key_exists() expects parameter 2 to be array, string given in /hermes/bosnacweb01/bosnacweb01ac/b1772/ipg.eafricartcom/e-africart.com/wp-content/plugins/yith-woocommerce-wishlist/includes/class.yith-wcwl.php on line 1156
if( ! array_key_exists( $regex_paged, $rewrite_rules ) || ! array_key_exists( $regex_paged, $rewrite_rules ) ){
flush_rewrite_rules();
}
Look like you are having the same problem when updated the YITH WooCommerce Wishlist Plugin to version 2.1.1
I solved this by modifying the line 1156 to: $rewrite_rules[] = get_option( 'rewrite_rules' );
Hope this helped.
