 * Hi, [@grrog](https://wordpress.org/support/users/grrog/),
    Sorry for that issue,
   Please follow my instruction for quick fix. open/wp-content/plugins/wc-order-
   export/wcexord_export.php this file and goto line number 131 copy the line
 * > $custom_meta = array();
 *  and paste before 128
 * > if( function_exists( “wcff” ) ){
 * Save the file, it will work.
 * Thanks
