Cannot use the website after changing username

[NaNomicon]

Hi, I recently changed my username (from NaN to NaNomicon) and I got blocked form using the website.

Now if I go to https://algora.io/, I got redirected to my old username dashboard https://algora.io/NaN/dashboard

Clicking Go Back Home doesn't help since I get redirected back to the old dashboard.

Manually going to my new username dashboard https://algora.io/NaNomicon/dashboard got me a 500 Internal Server error.

Update: Clearing the website data fixed everything. However it would be nice if I don't have to clear my data.
