PHP Warning: trim() expects parameter 1 to be string on line 488

  • I use this plugin and I’m grateful for its existence. However, I’m seeing the following error in my error log while using PHP 7.1+.

    [08-Apr-2019 12:17:31 UTC] PHP Warning: trim() expects parameter 1 to be string, array given in /.../wp-content/plugins/custom-post-order-category/wp-customcategorypostorder.php on line 488

    I hope we can fix this. There are other comparable plugins but as far as I know, there is no way to migrate/export my post order between this and any similar plugins.
