It works now. But I did see the wield behavior about 30 minutes ago.
I already logged in. and clicked the "search" icon, but it went to profile page. I tried multiple times.
Now I tried it agina - it's normal - i saw the search box showing and didn't see the profile showing.
Ah I see what you mean. Yes, searching requires a logged in account (unless set to allow guest searching in ACP), but there is no dedicated "search" page, I suppose...
