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

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
