 * Hi WC team,
 * I installed the Frontend Dashboard (I’m using WC Bookings and WC Product Vendors
   extensions) – all looks fine when I am logged in as administrator, but when logging
   in as a vendor admin, I see this error: “DataTables warning: table id=wcfm-coupons–
   Requested unknown parameter ‘1’ for row 0, column 1”
 * Do you know what may be causing this? I tested other vendor roles and all seem
   to have this problem.

 * Hi guys.
 * Had the same issue. They are related to cache issue. My issue resolved after 
   clearing and unchecking cache related boxes from on of my plugin. Hope this helps.

 * Hi brisden,
 * Thank you for your response. In my case it wasn’t a cache issue but permissions–
   Vendor Admins did not have permissions to view these for some reason. We added
   it via functions.php

 * Hi Weronika,
    could you please help me to share code to fix it on function.php
 * but my problem appear to admin and also vendor, this because maybe I submit database
   which is wrong name for this support-tickets after I saved/submit wrong value
   on apps flutter.
 * mine is :
    DataTables warning: table id=wcfm-support – Requested unknown parameter‘
   1’ for row 0, column 1. For more information about this error, please see [http://datatables.net/tn/4](http://datatables.net/tn/4)
