Warning “call_user_func_array()” re: “qw_admin_css" when WooCommerce installed

We’re using the latest Query Wrangler under the latest WordPress. We installed the latest WooCommerce. When we go to their Setup Wizard or any other of their admin pages, we get this at the top of all such pages:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘qw_admin_css’ not found or invalid function name in …/wp-includes/plugin.php on line 503

This function is, of course, defined in Query Wrangler (thus the “qw_” prefix). in ./admin/admin.php to be precise (and referenced via an “add_action” call in ./query-wrangler.php).

For now, since according to its name this function only affects CSS in the Admin panel for Query Wrangler, I’m going to ignore the warning and proceed with the WooCommerce setup. I’ll comment back here if there are any other issues. But this does need to be addressed.
