 * Hi,
 * This may indicate a conflict with another plugin flushing too early. As the function
   to flush the rewrite rules will only try this once, refreshing the page should
   in most cases resolve the issue.
 * if this doesn’t help, you can also try deactivating your caching plugin, as this
   is often the cause. Then activate SSL, and activate caching again. It sometimes
   helps to log in in an anonymous browser window.
 * Let me know if this helps!

 * Can you add the following to your functions.php:
    `update_option('rsssl_flush_rewrite_rules',
   true);`
 * This will tell the plugin not to flush.
