XF 1.2 One word/phrase causes 404 error

    I've been receiving emails from users, almost daily, about 404 errors that are occurring when trying to post a new thread.

    Screenshot attached.


    I went in and copied the thread text which the user claimed to cause the error and received the same result.

    After slicing and removing text from the thread, I determined that the following statement was causing the error.

    -- START

    System (

    -- END

    If I try to post a new thread which this simple word combo "System (" it trips a 404 error.

    Seeing that the error isn't produced here when I post this thread, I have to assume this is a configuration issue? Perhaps mod_security or something? Any way to see what other phrases are kicking off this error? Assuming that I am hearing about this daily, I have to assume there are multiple causes.

    I'd appreciate and be thankful for any leads!

    It's a 403 error ;)

    It sounds like a mod_security restriction to me. You should contact your host :)

    Darn typo! Thanks, I'll see if I can get some answers over there.

    Just wanted to update this: It was indeed mod_security that was causing the 403.
