Support » Plugin: Contact Form 7 » 409 Conflict Error – humans_21909=1

  • Hi,

    I’ve been using Contact Form 7 for many years now, and across 100+ websites.

    I’m facing contact form submission errors on almost all of my websites. When the Submit button is pressed, I just see the loading icon but nothing happens.

    When I look in the Console>Network I see 409 errors.

    /wp-json/contact-form-7/v1/contact-forms/61/refill:1 Failed to load resource: the server responded with a status of 409 ()

    /wp-json/contact-form-7/v1/contact-forms/61/feedback:1 Failed to load resource: the server responded with a status of 409 ()

    and this response
    <script>document.cookie = “humans_21909=1”; document.location.reload(true)</script>

    Sometimes, even the js/css/icons with the word “contact” in URL don’t load.
    409 wp-content/plugins/contact-form-7/includes/js/scripts.js

    If I access the individual files directly, they load just fine.

    When I use a different internet connection the forms work. I’ve asked my friends to test the contact form and it is the same for them. Works on Jio internet but not on Netplus.

    Any idea, how to fix the issue? I’ve emailed my internet provider, but I doubt they’ll be of any help.

    What other plugins and themes do you use on the sites?

    The form works if I’m logged in, or if I’m using Jio internet.

    Wordfence
    Flamingo
    Contact Form 7 Datepicker
    W3 Total Cache
    Classic Editor
    WPFront Notification Bar

    Just disabled all plugins, still getting the error.

    I’ve developed my own theme.

    Just installed Twenty Nineteen Theme, will all plugins disabled. Still got the error.

    Could the problem be related to hosting? The form works fine on my other website hosted on another host. What hosting setting should I look for?

    I can submit form without any error when I’m logged in.

    It could be. Who is your host?

    Bluehost. They seem to be blocking any URL with the keyword “contact”. On one of the website, a simple “contact.png” icon fails to load, but it loads when I open the image URL directly.

    They must have a system to stop contact form related spam, and are accidentally blocking genuine requests.

    See screenshot: http://oi63.tinypic.com/e6of45.jpg

    I also got this error.

    But, when I change network connection the problem solve 🙂

    @preetindersodhi Did you ever resolve this issue? I am encountering the same thing. My web host (Host Gator) is saying this is not due to anything on their end.

    @cag8f No. I still face this problem sometimes. It happens on some IP addresses. I talked to Bluehost last time, they said my IP was blocked due to spam related activities. My internet connection has dynamic IP, someone else might have been spamming.

    Bluehost and Hostgator, both owned by one company. I face this problem only on Bluehost. No issues on Bluehost VPS or iWeb.

    Update:
    I checked log of some of my websites and found out that the 409 error is not limited to Contact Form 7. I’m quite sure it is hosting related issue.

    See my post for details: https://www.geminigeeks.com/bluehost-blocking-contact-form-7-submissions-409-conflict-error/

    For me, the 409 error is confined to these three plugins, all contact form related:

    Contact Form 7
    Contact Form 7 Datepicker
    International Telephone Input for Contact Form 7

    >> I talked to Bluehost last time, they said my IP was blocked due to spam related activities.

    OK. But in that case, shouldn’t that prevent you from downloading *any* file from the server?

    The block the URLs with the word contact. They blocked a CSS file and an image file on my site, the image had nothing to with the plugin. It was a contact icon.

    Talking to Bluehost, they are not being helpful, asking me to contact my ISP. I’m trying to get them to review their security rules.

    This is what they said:

    I have reviewed your issue, upon my review I found that the issue occurs when its been accessed by dynamic IP address, I would suggest you to contact ISP and ask them to assign static IP to your network, If your IP is frequently switching to different IPs and it happens to load 409 error, please check if the issue persists with static IP address. Our shared servers are having more security restrictions compared to our VPS servers and it may not occur on VPS account, since the remote access is typically less secure on dynamic IP address.

    I understand you would like to explain your issue with the remote view, Unfortunately we are not authorized to use TeamViewer from our systems. However we can get back to you via call if you still wish to investigate further on this issue, please let us know the good phone number and time(with time zone) to get back to you.

    Hi I also had the same problem but I had a VPN connected. When I turned it off it finally loaded. If I could get the website to load with the VPN I would be helpful because many use VPN as protection. I only have this problem on the contact page of my website. same script shows <script>document.cookie = “humans_21909=1”; document.location.reload(true)</script>

    having same problem. They blocking any URL with the keyword “contact”. On my website, a simple “contact-banner.png” image fails to load, but it loads when I open the image URL directly on a new tab. Please give me some solution.
