Error: sed: -e expression #1, char 86: unknown option to `s'

Ok, thank you for this improvement: It works now when I keep only the values I changed. I will remove the previous hack.

Regarding quotes, I do not see any uncommented item with a quoted string value so does it really matter?
For example, in my pod, no match for:

egrep '^[^#].*"' /usr/local/tomcat/webapps/ROOT/WEB-INF/xwiki.*

I have not used quotes for items like the superadmin password and this is working anyway.

I think the original problem remains tough: if a user edits a value with the usual syntax, at least entries containing pipes will raise a problem due to the clash with the sed separator.
