404 error when trying to view Newsletter Subscribers in the admin

404 error when trying to view Newsletter Subscribers in the admin

When I go to marketing -> Newsletter Subscribers I can see the first 20. But if I try to go to the next page in the list, or extend the display results to a number greater than 20, I get a 404 error. I also get an error when I try to export to a csv. All other import and export functions in the admin work without issue, same with viewing any other lists. subscribers404error.jpg

Hi @etchalifou5534 

Please check with controller 

vendor/magento/module-newsletter/Controller/Adminhtml/Subscriber/Index.php

You need to check conditions of ajax, is it working fine or not.

 if ($this->getRequest()->getParam('ajax')) {
            $this->_forward('grid');
            return;
        }

Also check with Block file functions.

vendor/magento/module-newsletter/Block/Adminhtml/Subscriber.php

It may help you to resolve issue.
