UBB.threads PHP Forum Software Community Forums UBB.threads 6 Version 6 Bug Reports UBB.threads6 on PHP5? Not working?

Can you or somebody else please give me some info about the thing you call open_basedir? I'm sorry but I'm not an advanced webmaster, I know PHP/mySQL scripting a little though, but I have never heard of anything like this. Do I need to contact my server admin about it?
