I have to report another error after I installed and unistalled apache2-suexec-custom:
<root># service apache2 restart
Syntax error on line 8 of /etc/apache2/sites-enabled/john:
Invalid command 'SuexecUserGroup', perhaps misspelled or defined by a module not included in the server configuration
Action 'configtest' failed.
The Apache error log may have more information.
If I disable john's site then apache can do a restart!
This error wasn't before, so what's going wrong now I wonder?
