 * I have tried this on my localhost using memcache and it’s very quick.
 * Unfortunately, my live host uses XCache, and I note you say the plugin is still
   unstable with that. Indeed, I’ve just tried it on my localhost and got the white
   screen of death.
 * You mention you’d appreciate volunteers to test out this plugin with XCache. 
   So, if that offer is still open, I’d be interested in being one if you could 
   let me know what you’d like me to do.

 * Yes, thank you!
 * Can you please check the errors logs to see what causes the white sceen?
    Turning
   on WP_DEBUG might also help.

 * OK, this is what I got after turning on debug mode, activating WP-FFPC and saving
   the default settings (which are set to PHP Memcache):
 *     ```
       Notice: wp-ffpc init starting in /var/www/html/webby/wp-content/plugins/wp-ffpc/wp-common/wp-plugin-utilities.php on line 59

       ```
   
 * After changing from PHP Memcache to XCache, I get the white screen of death with
   this message:
    `Fatal error: xcache_info(): xcache.admin.user and/or xcache.admin.
   pass settings is not configured. Make sure you've modified the correct php ini
   file for your php used in webserver. in /var/www/html/webby/wp-content/plugins/

 * Have you tried setting the xcache.admin.user and the xcache.admin.pass in the
   php.ini?
    Xcache needs that in order to have the user cache work.

 * My mistake! I assumed that the plugin did its own configuring.
 * I’ve set them both up now, and the site is now working, but I get these messages:
 *     ```
       Notice: wp-ffpc init starting in /var/www/html/webby/wp-content/plugins/wp-ffpc/wp-common/wp-plugin-utilities.php on line 59

 * Just in case it helps, Query Monitor reports the following in addition to the
   debug messages:

 * xcache documentation is one of the shittiest I’ve ever seen.
 *     ```
       /**
        * Get cache info by id on specified cache type
        *
        * @param int $type
        * @param int $id
        * @return array
        */
       function xcache_info($type, $id) {}
       ```
   
 * and I cannot find any information on what type and id indicates there.
 * I’m very close to drop xcache support.
 * Any idea what do they represent or how to test if xcache is happy in another 
   way?

 * Thanks for looking at this. I’ll talk to my host and see if they have some ideas.

 * Peter,
 * I have now had a good conversation with my host. They were, as always, extremely
   helpful.
 * But, to cut a longish story short, I think it probably does indeed make sense
   to drop support for XCache.
 * Thanks for your hard work!
