Hi @MiloCat sorry for the delay in picking up this issue. Are you still experiencing the problem?
I’ve been tidying up Repls recently as well (limits) and haven’t had the 500 error when deleting mine so wondering if it might be related to a specific browser?
I’ve been experiencing somewhat of a similar issue recently, after deleting a Repl I see the following screen for around a second, before being immediately redirected to the homepage.
