Hello, @zekikaynak,
Thanks for your contact.
First of all, your provided WP Admin Login details are not correct/working: https://postimg.cc/QKc6S5g7
And I have checked your site and found it is working perfectly fine for me, the user icon in the header takes me to my account page when clicked on it, please refer to this screenshot: https://postimg.cc/w7YpcQ5w
So it seems you have managed to change it right?
