    Good morning,

    First thank you for your really awesome plugin!

    I’m having problems with an unknown action that purges my cache regularly during the day, it’s very annoying since visitors have to load the page each time they visit.

    In the purge log (page cache) here is an extract of what (apparently) causes the purge: 

    Date

Tue, 12 Sep 2023 10:03:42 +0000

Action

flush_post(53898)

    At each of these purges, the log displays around ten similar actions (at the same time, only the post number is different). The above snippet involves post 53898 (flush_post(53898)) but I also have the same thing for posts 53897, 53896, 53895, up to post 53888.

    This is repeated several times during the day and the numbers of posts involved go up.

    I specify that the posts which are mentioned in this purge log do not exist (in any case were not created by me, and I am the sole administrator).

    I haven’t found what could be causing this.

    I installed WP Crontrol to try to find the cause but I couldn’t make any progress in that direction.

    Here are the crons present on my site (I should take advantage of this to clean up, yes…).

    Would you know how to help me please? I’m not a coder or developer and so I quickly get lost and stuck.

    Could the problem come from something else?

    I can provide further information if necessary.

    Hello @erua97

    Thank you for reaching out and I am happy to help!
    The W3 Total Cache purges the post cache once the post is updated or a new post is created, and this behavior is managed by the Purge policy in Performace>Page Cache.

    SO it appears that something was updated on those posts, possibly automatically which causes :

    wp-includes/post.php(4751)

do_action ("save_post", 53898,

    And this triggers the 

    flush_post

    in the W3 Total Cache. Can you please share the Performance>Page Cache>Purge policy screenshot and possibly the website URL

    Thanks!

    Hi Marko and thank you for your response!

    I’m sharing a screenshot below of my purge policy : https://snipboard.io/EB7lXz.jpg

    Please note though, I have tried unchecking everything but it keeps happening.

    The home page link is: https://letresoretudiant.fr/

    Also note that, as I have just visited this page as a visitor, the cache may still be active when you go to visit for yourself

    I remain at your disposal for further information.

    Hello @erua97

    Thank you for your feedback.
    The Frontend_Form widget acf-frontend-form-element-pro plugin, which updates some post while it renders itself. and it causes purge.

    You should check the post type of those posts by checking select * from wp_posts where post_id in (53898, other ids)
    high probability it’s some “cache storage” for the menditoned plugin.
    and it potentially can be filtered out from purging by post type.

    You may want to check this code in their github


    Thanks!

    Hello @vmarko,

    Thanks again. I checked my posts table, all these posts are not present, the query tells me that all these posts do not exist.

    I dont know what to do…

    Regarding the code that you provided via Github, I really have very little knowledge of coding, so I admit that I don’t really know what to do with it.

    How to filter these “posts” from purging while they “don’t exist”? That’s a bit disturbing?

    Thanks again for your help Marko!

    Hello @erua97

    Thank you for your feedback.
    This is why I mentioned that they may be in some cached areas other than W3TC.
    In the GitHub link, you can see the function
    public function flush_post_cache( $post) I would strongly suggest reaching out to acf-frontend-form-element-pro support and checking with them what may be occurring to call the post flush and if those posts are in some sort of cache.

    I hope this helps!

    Thanks!

    Hello !

    Is there a way to prevent the flush_post_cache function for all actions that call this function? My problem is still not resolved and I have not found any solution despite a lot of research…

    Thank you so much…

    I think I have identified the chain of events that is causing the problem:

    The acf-frontend-form-element-pro plugin generates the ‘acf_update_field’ action.
    In response to this action, the advanced-custom-fields plugin calls the wp_insert_post function from the acf-field-functions.php file.
    The wp_insert_post function generates the ‘save_post’ action.
    The W3 Total Cache plugin intercepts the ‘save_post’ action via the W3TC\Util_AttachToActions–on_post_change hook and triggers the ‘w3tc_flush_post’ action.

    What remains for me to do?
    Life is not easy when you are not a dev 🙁
