Forum user name

I have just changed my display name, however I noticed that my forum profile name is not being updated. How can I fix this?

Looks to me that it has changed too, so you maybe should reload a page or clean the browser cache?

Topic I made after I changed display name have used my new display name, however if you go to my profile and check my older posts then you can see they are not changed

I see. Please contact admin Hakuch directly to solve it.

I have sent a message to the admin a while ago but still haven’t heard back from it and the situation is still no different from when I started the thread.

I have no other way to contact him.
