'Reply' link is visible for locked threads if you are logged-in. STR: 1. log into SUMO stage 2. go to https://support-stage-new.mozilla.com/en-US/forums/test-forum/217 which is a locked thread 3. click on 'Reply' 4. Post some text and hit 'Reply' Actual result: You land on a plain page without CSS saying 'You Screwed Up' Expected result: 'Reply' link should be disabled for locked threads.
Actually, it isn't possible to reply to locked threads. However, non-authenticated users can see 'This thread has been locked. It is no longer possible to post new replies,' when no message should be displayed.
Scratch the description in comment 0. locked threads should not display any message to unauthenticated users STR: 1. go to SUMO stage (log-out if you are logged-in) 2. go to a locked thread like https://support-stage-new.mozilla.com/en-US/forums/test-forum/217 Actual result: You see the message 'This thread has been locked. It is no longer possible to post new replies.' Expected result: Users who are not logged-in should not see this message.
Correction once again. You get the message 'This thread has been locked. It is no longer possible to post new replies.' for any thread when you are logged-out not just the locked threads.
