Hello to you all,

I got an erro message while trying to install zenario ( Suspecting the source to be the .htaccess file, I ran it through this online htaccess checker (

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"?

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



(By the way, I'll add a note about this to the system requirements.)
