Getting blank page when previewing

    Hi. Awesome plugin. Some of my editors are seeing blank pages when they go to update a page or post. I’m not having the same issue. The only thing different from me to them is I’m whitelisted and they’re not. I think by adding their IP fixes the problem temporarily but IPs change. Is there something they’re doing that’s tripping this?

    Thanks,
    Bob

    Hey Bob,

    How have you configured the plugin to react when it firewalls? Just die?

    Cheers,
    Paul.

    Great question Paul. Yes. Should I leave it on a message to throw us a clue?

    Hey Bob,

    Yep, put it on the message so we can see a little bit clearly that it’s being blocked by the firewall.

    If you’re interested, you could could add a whitelist rule for that page/parameters and see if that solves it. Check out the FAQ

    The log would probably also tell you what the parameter is that’s being blocked… then you could do:

    post.php, blocked-parameter

    in your parameters white listing.

    Also, remove yourself from the IP whitelist so you can experiment with the whitelisting 🙂

    Let me know how that works.
    Cheers,
    Paul.

    Paul, I just ran across the problem that’s been occurring. I wasn’t seeing it because I had whitelisted my IP when setting up the plugin.

    Once I removed my IP from the whitelist, started recording logs, and added a message to the “die” function – I started seeing clues.

    The error message is: “Something in the URL, Form or Cookie data wasn’t appropriate.
    “

    The log recorded the page html code and this:
    Page parameter failed firewall check.
    and the term matched was /0x[0-9a-f][0-9a-f]/i

    Any ideas? I’m getting this problem on every site I use your plugin on…

    Thanks,
    Bob

    Okay, it’s matching on one of the WordPress terms and it’s probably because you have an image in that page.

    For now, if you turn off the sub-section that does the WordPress Terms checking in the firewall you should be ok. I’ll add a rule into the plugin to cater for this in the next release.

    Cheers,
    Paul.
