I would like to add some new, related info - everytime I visit the page Servers -> localhost -> Switch program, I noticed that this file always get re-created in the server:
/usr/local/lxlabs/kloxo/etc/flag/use_apache24.flg
even if I know I don't have httpd24 installed. I have some machines that still use httpd, and I notice Kloxo replaces httpd with httpd24 when I run certain 'fix' scripts from /script. I'm thinking this flag file is causing the switch to httpd24.
This happens on httpd servers and nginx servers. Running the 'cleanup' script does not fix this problem.
