Ok, here's a new one on me. In trying to figure out yet another case of cgi-bin scripts giving 500 errors (premature end of script headers), I have discovered that the /usr/sbin/suexec and /usr/sbin/psa-suexec are actually hardlinked (same inode number). Can someone else with Plesk 7.5.3 verify if theirs is the same? and see if the inode numbers are the same on yours?? If not, then I don't have a clue as to how this happened. But I am assuming that my psa-suexec is now hosed during one of the last updates... (yes, I've tried ALL of the other hundreds of suggestions and none work, the last thing was the suexec issue) Thanks!
