 * wp 5.9.3
    wp-cloudflare-page-cache 4.6.1 wp-multi-network
 * I had problem with preload, probably is running per site and after restart 2 
   weeks ago, it’s overload server with lot of requests. I disable it but requests
   from localhost “POST wp-admin/admin-ajax.php?action=wp_swcfpc_cache_preloader_background_process”
   persist. I need comment main instance in libs/preloader.class.php.

 * Huh! That seems wired. As if you have disabled preloaderinside the plugin settings
   i.e. [https://i.imgur.com/19R4vWM.jpeg](https://i.imgur.com/19R4vWM.jpeg) – it
   won’t run.
 * Beside preloader is something I never recommend running if you have a big and
   good traffic site. It is mainly for small sites which doesn’t get much visitor
   and it is also very resource intensive as it uses cURL.
 * So, if you have disabled the preloader from the plugin settings check if you 
   have any cronjob set that might be triggering the preloader.
 * Finally also just do enable/disable page caching form inside the plugin settings
   page.

 * I disabled preloader (this remove get /autor/feed requests) and disk cache over
   gui, but didn’t resolve problem.
 * I look into cron and I found there is swcfpc_purge_cache_cron_interval, but it’s
   related to disabled disk cache. cf_disable_cache_purging_queue is 1 and i did’t
   find purge_cache_queue_start_cronjob string in logs.

 * Have you tried disabling and deleting the plugin complete via wp-admin and then
   adding it as fresh? Does that solve the issue?

 * I honestly have no idea how the background process can be running if preloader
   is turned off in the plugin settings and you have not set preload via cronjob.
 * Also when you turn on the preloader option inside the list of sitemaps to mention–
   that section is blank right? I mean nothing is there and then you have disabled
   preloader?
 * Honestly, I don’t know what I am saying… I’ve checked the code multiple times
   and see no way of this being possible while preloader is off in the plugin settings.

 * I disable option as you requested:
    from “cf_preloader_nav_menus\”;a:2:{i:0;s:
   1:\”2\”;i:1;s:1:\”3\”;}” to “cf_preloader_nav_menus\”;a:0:{}”
 * from “cf_preloader_start_on_purge\”;s:1:\”1\” to “cf_preloader_start_on_purge\”;
   s:1:\”0\”
 * from “cf_preload_last_urls\”;s:1:\”1\” to “cf_preload_last_urls\”;s:1:\”0\”
 * The problem persists.
 * I found that POST request loop is begin only when site is accessed.
 * I try to revert back developer instance to last functional state and “problem”
   is in DB (php files are same). I found only relevant difference in table wp_612_options:
 * —ok system:
    swcfpc_preloader_lock 0 —problem system: swcfpc_preloader_lock 1656681270

 * The `swcfpc_preloader_lock` will only invoke when the preloader is enabled in
   the plugin settings. If the preloader is off in the plugin settings then this
   should not invoke.

 * It looks like the problem is fixed, with :
 * update wp_612_options set option_value = ‘0’ where option_name = ‘swcfpc_preloader_lock’;
 * Thank you for your help and your time.
