I don't think so - I've used AdBlock Plus AND Ghostery together for as long as I've been a member here and this was well before I was made a "Site Team" member too. I've never been logged off the site, no matter how long I've been connected and no matter what I'm doing. I use FireFox as my browser, if that makes any difference too.
You caould certainly disable your ad blocker on the site to see if that makes any difference.
