User Register Complete Not Working

Description of issue or problem I’m having:
If there are new users who register in my journal and succeed, they do not go to the registration complete page.
The user actually returns to the user/register page. As a result, many new users think that they have not successfully registered, when in fact they are already able to login.

Steps I took leading up to the issue:
Here is a simulation link that you can see.

Can you help me, here’s if you want to do a simulation.

What I tried to resolve the issue:

I have tried several things:

  1. Replace all folders with new OJS 3.2.1.2 files
  2. Deactivate some plugins, such as orcid profile, user register notification, and several others
  3. Upgrade to 3.2.1.4

Everything that has been done does not solve the problem

Application Version - e.g., OJS 3.1.2:

OJS 3.2.1.2

Additional information, such as screenshots and error log messages if applicable:

Hi @solehhasan,

I don’t think this is an error, the user is able to login upon registering - I’m afraid I don’t understand what you think the issue is?
