Well I guess this isn't a site-wide issue and probably just something to do with my settings but I couldn't be bothered to make a whole new thread on this.
It used to be that when I was for example searching a name in the member list and I would start typing out a name, a little box would appear underneath the input bar giving me names starting with the letters I had entered.
Well, that's not happening anymore for me.
In case the above wasn't clear enough, I think it's the same thing which when you start writing a tag, would give you the names of tags that have already been written. Some ajax thingie or so? Not sure...
How can I get this to work again?
