@faizanzahid Those in the screenshot are the global privileges. You want to change the category privileges, selecting each category (see up to the right), at least the root ones. There is also a button to copy privileges to the children categories.
@meetdilip Yours definitely seems slower than it should be. I just tried and got 5.15 seconds, but each of your requests takes slightly longer. you're on digital ocean correct? Which server did you go for? Amsterdam 2 or New York?
My homepage is loading in 3.18 seconds, but each request is completing faster for me.
Getting socket.io for example took 900ms on your site, but only 163ms on mine.
Thanks @a_5mith . Could please tell me what I should do. I use default lavender theme with just colours changed. Is that the plugins that is slowing down forum ?
