Ran "yum update" from the standard ART repository, everything updated ok on the command line but now httpd refuse to start. From PSA I get From the shell I get even less, just a message that it "failed". No help in /var/log/messages either. It's not the first time I update Plesk servers this way, but first time it has created problems. Would appreciate hints to what could have gone wrong and/or where to look for more debugging info about this., TIA!
