We recently moved servers, but despite migrating our old PHP.ini settings to the new server, we are getting session timeouts after a few minutes with webim. It seems that simply refreshing the page seems to re-login on the "awaiting visitors" page, but this does cause our "live chat" button to disappear from our site. I've checked the settings that have been suggested thus far in this thread, but we have nothing that deviates from the recommended settings. Any ideas on what this could be?
