The precondition on the request for the URL /forums/post/discussion/5 evaluated to false. Additiona

Hey there,

sometimes when posting in my forum, it won't post. instead, this message pops up:

"The precondition on the request for the URL /forums/post/discussion/5 evaluated to false.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.
"

Does anybody know how to solve this?

    this is more a of a server error rather than vanilla specific. probably to do with you .htaccess.

    could be related to mod_security

    you could try adding this to your .htaccess
    <IfModule mod_security.c>
    SecFilterEngine Off
    SecFilterScanPOST Off
    </IfModule>

    grep is your friend.

  • Thank you.

    Didn't work unfortunately :(
  • talk to your host.

    grep is your friend.

  • Worked to talk to website host.

    However, I still find this problem when trying to type in certain characters, in particular a " % ".

    Fortunately this can be replaced with the word "per cent", which will solve the issue if this is the problem.
