 * Hi customer support
 * We use the wp-optimize plugin.
    I have a problem, please help me. Please let 
   me know if there is a difference between the paid version and the free version.
 * I have such a problem.
    When I use the preload function, the load on the database
   increases and the site goes down.
 * I have three questions.
    First question.” Purging the cache”.
 * Is it possible to delete the cache only for updated pages? Does the free version
   have that feature?
    Please tell me if there is a difference in the paid version
 * The second question. About “preload”
    Is it possible to adjust the preload loading
   speed?
 * The third question. About “preload”
    Please tell me how to set the preload setting“
   wp-optimize-wpo_last_page_cache_preload_type”. I want to change from “sitemap”
   to “posts”.
 * I am waiting for your reply.
