Checkout form pre-filled with old visitor’s data

    Hi everyone,

    I’m trying to solve an annoying problem that affects my site (and others as well, see below). The visible effect of the problem is that, in the checkout page of the woocommerce plugin, the field of the form are pre-filled with old customer’s data.

    I think the problem is similar to these post’s:
    – Same problem but I don’t have that plugin (form editor)
    – Seems similar but I don’t have Gravity
    – Like this one but happens also to logged in users

    To prevent everyone from loosing their time I clarify which causes I would exclude (because already checked):
    1. Caching problem
    2. Browser problem
    3. Mobile or desktop site is the same
    4. Different languages don’t change anything
    5. The woocommerce database and plugin versions are the same
    6. The error occurs also with default theme with all other plugins disabled

    I noticed a weird behaviour in the table “wp_woocommerce_sessions”: sometime, for example when a guest user goes to the checkout page, aside the real session, magically appears another session with “session_key” value 1 (should be 7 if it was a real new request) and the information are exactly those displayed (the wrong ones). Other times the session is perfect (holds the right info) however the filled values are the old ones.

    For completeness here I append the woocommerce status, feel free to ask for details, I’ll provide the needed information as much as I can.

    Thanks

    @nic0net Were you able to get this resolved on your end? From the sound of it, you have looked over caching and the information stored in browsers. The only other thing I can think of in this instance would be that the sessions table is not auto incrementing as it should, causing sessions to be passed from user to user. You could get your host to help you with seeing if the table is set to auto increment.

    Hi, What was the solution to this. I have exactly the same issue??

    Thanks

    Hi, I am also having this issue. I have found others with this issue but no solution yet even though they are marked resolved. Anyone have any thoughts?

    I am having the same issue. Is it sessions related? This is a crazy error. I could only replicate it once and now I can’t do it again but customers are reporting that other peoples private data is displayed on their screen. : (

    So frustrated with this!

    Was this resolved? We are still experiencing this issue …

    This is not resolved for me. I am still having this issue.

    I have also submitted a new post on this. Sorry.

    We had the same issue and narrowed it down to Sucuri Caching. Once I disabled Sucuri Cache it solved the issue. We already had WP Fastest Cache running which may have caused a conflict?

    I just encountered this issue with a client today. Hope this helps someone out.

    If you haven’t already temporarily disabled caching plugins on your site, then I recommend doing so.

    Also visit the server host (Bluehost, Siteground, HostGator, etc.) and temporarily disable any server-side caching like NGINX.

    If the issue still exists, try adding this line of code to the site’s functions.php in the theme editor as a permanent solution:

    // Custom functions
add_filter('woocommerce_checkout_get_value','__return_empty_string', 1, 1);

    This will remove any pre-filled data on the checkout page.

    The last step should solve your problem but is more of a last resort option if you’ll never need pre-fill info on the checkout.

    A third option is to clear any Woocommerce caching. Go to WooCommerce -> Status -> Tools and you can find all the caching options here. I recommend you backup the site with All-in-One WP or another plugin to prevent any issues before clearing these options.

    For more information and resources check this Stack Exchange Post:
    https://stackoverflow.com/questions/43314610/remove-woocommerce-checkout-fields-values

    This issue is definitely a caching problem so I recommend narrowing down which plugin (client-side) or if it’s your server (server-side) and go from there.

    Best of luck!

    @meerkhatdesign we just had this happen again. Our host enabled NGINX on the server and we were running WP Fastest Cache and it leaked previous customers data again!

    This is horrible from a customers perspective. I wish Woocommerce would do something about it.

    Do you know If we should not run any type of Server-side cache? Our host wants to enable Cachewall instead of NGINX.

    We have the same issue we disabled all the cache and flushed it… couldn’t replicate on desktop but it was intermittent on mobile.. Still not resolved used the code up top thank you for that. But you would think this is a woocommerce issue and should be updated by them.
