Ничего не происходит при клике на синие ссылки в теме письма в разделе /admin/email-logs/received

Received email can't be viewed in the Email logs

Thanks for reporting it! It seems we are unconditionally wrapping the subject in a link even if there’s nothing to link to… We’ve added a fix, which will be included the next time you update Discourse https://github.com/discourse/discourse/pull/36324
