I guess locking the conversation is useful where an admin/mod wants to send announcements to users.
@Admins:
Has Forum software changed yesterday??
I'm having grave trouble contributing.
1) When I reply to threads, I get a strange preview pop-up wthen submitting, and I have to click this away in the X in the upper right corner. Once gone, the normal thread view is not updated, but still has the editing window in it allowing me to double or triple post. Pressing F5 (refresh) will provide the correct view, though.
2) I can't create new Threads (I wanted to for this error report, but as I can't, I had to use TJs old). When I press "create thread", I get a thread creation box I've not seen before, and an "oops, internal error" message.
This has been going on since yesterday or friday...
I'm running Firefox 58.0.2 on Linux Mint (64-bit).
