# Plugin rewrite rule flushed on plugin/wp update

 * My plugin sets rewrite rules using add_rewrite_rule, on plugin activation the
   rule works great.
 * Often these rules stop working which seem to coincide with a WordPress update
   and/or a Yoast SEO plugin update.
 * Is there any way to set the rewrite to not be flushed by another source, or is
   it possible to check via cron job in my plugin whether the rule exists, if not
   then set it again?

 * You can use ‘upgrader_process_complete’ action to do something after upgrades.
   Your callback is passed an instance of the upgrader object and an array of data
   about what was upgraded.
 * You cannot prevent the rewrites from being flushed though, it shouldn’t be necessary
   AFAIK. Your add_rewrite_rule() is still considered when rewrites are flushed 
   if your plugin is active. And if it were deactivated during upgrading, your activation
   hook should be triggered upon reactivation, so you’d be covered either way.
 * Something about how you phrased your question gives me pause. Your add_rewrite_rule()
   calls should be made from the “init” action every time your plugin loads. Not
   only during activation. What you should only do during activation is call flush_rewrite_rules().
   If this is what you are doing, I don’t know what is causing trouble, but something
   else flushing rules shouldn’t matter.
 * You could use the above hook to flush rules again, but it shouldn’t be necessary.
   Flushing is time consuming and upgrades are prone to timing out as it is. Lets
   try to not make the problem worse 😉
