andreyP is the user is using a shared host that is not setup to run the dolphin script, then this could be true. however, in going by the developers own server requirements, this would never present itself as a problem. and a script running as nobody. the instance you speak of this server could and should on a shared environment be minimum SUPHPexec and that would alleviate what you are saying. so you tried on one server that was not configured to run dolphin. i have used this scirpt on 150+ servers, see more and found one problem only once.

just wanted to bring that to your attention.
