I'm developing a site with PHPBB and using full site integration - using the PHPBB login details to authenticate across the site. This works absolutely fine in the live environment but fails on my test server. I think I've tracked this down to my local server not being able to set a cookie and this is borne out by PHPBB as it passes a sid around in the URL locally but doesn't in the live version. The Apache server is running on a local network, on Win2000 and appears to work in all other respects except cookies. Can any kind person point me to some likely reasons why this ain't happening? All the usual stuff like paths and so on seem correct but I'll admit you can use the back of a stamp to detail my knowledge of Apache installation so... Jon
