I had cacti installed on my ArchLinux box but I don't know after upgrading my system php include_once() has stopped working and it doesn't include files any more.
However if I replace include_once() with include() things start working again, but some files get included twice which causes some other issues.
I don't know how this problem can be fixed, I've almost tried everything but can't get it to work, can someone help me fixing this problem please.
