Hi there Alex
Yes you need this line, it's there for security reasons. Your site can be vulnerable to a type of attack called clickjacking without it set.
If you're running an older version of Apache (before 2.4.7) that doesn't support this feature, try using this instead:
<ifModule mod_headers.c>
Header set X-Frame-Options SAMEORIGIN
</ifModule>
(By the way, I'll add a note about this to the system requirements.)

Hello to you all,
I got an erro message while trying to install zenario (zenario-probusiness-7.7.43763.zip). Suspecting the source to be the .htaccess file, I ran it through this online htaccess checker (http://www.htaccesscheck.com/).
Reported error on line 4: Header setifempty X-Frame-Options SAMEORIGIN
Error message reported: Fatal: first argument must be add, set, append, unset or echo.
I commented these lines at the top of the file:
# <ifModule mod_headers.c>
# Header setifempty X-Frame-Options SAMEORIGIN
# </ifModule>
Et voilà, it worked.
My question is: "How important is this Header setifempty X-Frame-Options SAMEORIGIN"?
Regards,
AlexDP
