    At In response to, whenever I attempt to preview my draft response – with the text that's currently at – there's a problem:

    Sucuri WebSite Firewall - CloudProxy - Access Denied

    Most recently at I see:

    If I use dummy text for the draft, preview succeeds.

    I can't see what's wrong with the true text of my draft. TextWrangler finds non-ASCII characters but no other type of gremlin.

    Any ideas?

    That Sucuri is a forum security setup used here, but I'm not sure why it would be blocking your post.

    I've asked the admin staff to take a look at it for you Graham.

    The last bit in CODE tags is triggering the block because Sucuri thinks it's malicious code. I'll ping arn about it once he's around and see if there are any tweaks we can make.

    Actually, this has happened to me a few times in recent weeks as well. I had wondered what it was, but never thought to mention it here. Thanks for raising it.

    Sucuri problem with two dots .. in a string

    Thanks for reduction. I reproduced the problem without markdown.

    No problem with the following string:

    sh-3.2$ cd $TMPDIR/./C/

    – but that's not the required string. Make it two dots (parent directory) instead of one –


    and preview of the string will be blocked.


    For myself I worked around the problem by linking from today's to
