Image Import Php Error In Exim.php

We’re unable to import images and the error log shows this :

PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘fn_import_check_product_company_id’ not found or invalid function name in /xxx/public_html/cscart/app/controllers/backend/exim.php on line 1638

We haven’t changed that file. Does anyone know how to correct this?

MV 4.2.4 and we’re importing via admin for All Vendors.

Disregard - support figured it out.

what was the issue?

Sorry - I’ve been swamped with our site launch.

It was a custom add-on; all fixed now! :)
