Just a blank page with "Internal Server Error" -- no other messages.
Hi, thanks for reporting this.
I believe this was a result of an edge case when a user changes their e-mail without first validating their old e-mail. I think the following commit solves the issue: https://git.sr.ht/~mlb/linkhut/commit/267456273dea9b9ae1e425696fe810a9560df244. Could you try again to verify that things work as expected?
Thanks!
