how to lock a post (solved)

i cant found the lock button can someone tell me how to lock a old post please.

hello,
the lock button is in bottom of the page on the left!



if you don't got this buttons (What is odd, checks that you didn't put an empty GIF at the place!) you can do it also by : clicing "moderate this forum"



then select the forum you whant and Lock!!
