Plesk control panel displays 500 - Internal Server Error

[PaddingtonC]

My Plesk 9.5.4 control panel running on Ubuntu 8.04 LTS the error " 500 - Internal Server Error" when I try to view it in a browser. The websites on the server are working but its just an issue of going to the control panel. How can I resolve this?

Reboot the server, or preferably just restart the Plesk web server software 'sw-cp-server' and 'psa' services. I'm not familiar with Ubuntu but on RHEL you'd:

/etc/rc.d/init.d/sw-cp-server stop
/etc/rc.d/init.d/psa stop
/etc/rc.d/init.d/psa start

which will bring back up both of them. We see this regularly on 9.5.4 where Plesk just random starts giving 500 errors. I'm sure Parallels will just tell you to upgrade to 11 to fix the issue.

Hi, there

yesterday, i was trying to modify template of new hosts,
but i seem did something wrong,

i decompressed /usr/local/psa/tmp/default_skeleton.tgz, then mkdir tmp,
since then, i can't log into my control panel.

it always show 500 internal server error,

i did ./bootstrapper.sh repair, but it doesn't help.

then i found out that there are some error, when i trying to start psa

here it is,

2013-10-31 10:17:01: (mod_fastcgi.c.1000) the fastcgi-backend /usr/bin/sw-engine-cgi -c /usr/local/psa/admin/conf/php.ini -d auto_prepend_file=auth.php3 -u psaadm failed to start:

2013-10-31 10:17:01: (mod_fastcgi.c.1007) if you try do run PHP as FastCGI backend make sure you use the FastCGI enabled version.
You can find out if it is the right one by executing 'php -v' and it should display '(cgi-fcgi)' in the output, NOT (cgi) NOR (cli)

2013-10-31 10:17:01: (mod_fastcgi.c.1012) If this is PHP on Gentoo add fastcgi to the USE flags
