Juhtus selline asi, et ühe virtualhosti seadistamisel annab error 500 ning logis:
[Wed May 19 11:11:39 2010] [warn] (104)Connection reset by peer: mod_fcgid: read data from fastcgi server error.
[Wed May 19 11:11:39 2010] [error] [client 192.168.0.177] Premature end of script headers: test.php
Ja noh ei saa aru mis viga on.
Lõpuks selgus, et virtuali cgi-bin ning seal asuv wrapper peavad olema 755 õigustes.
