Hi,
Please make sure that you added this code snippet with the Code Snippets plugin, you can check this tutorial - How to add custom code snippets - HivePress Help Center
Also, please note that this snippet will break some user flows.
For example, by default after registration, you will be redirected to the form to fill in the profile, if you add a custom redirect, then you will need to return to this form again to fill in the data.
