Hi,
We have just tested registration feature on your website and it is working perfectly fine. You can verify a new user ‘aazztech_test’ from dashboard > all users. Here is the screenshot: https://prntscr.com/kqqb3t
However, we have found two issues on your site.
1. The mailing feature is not working on your site. Please contact your hosting provider for this issue. Or hire a developer to debug it on your site.
2. The URL of the Front-End user dashboard is not properly set, therefore, a user is redirected to a wrong page. Please make sure to set it properly from Directorist Listings > Directorist Settings > Pages, links & views > Add dashboard page ID settings option.
Thanks
