 * I installed this plugin yesterday, and my assets are still pending minification.:-/
 * I have wp-cron running, of course.
 * When will the minification run? What if I manually minify the files in `uploads/
   mmr` myself?
 * Thanks.

 * Hi. MMR should start showing minified files within 2 minutes. It sounds like 
   yours hasnt completed. Try purging a file and watch the logs.

 * Also, don’t put your own files in the MMR directory. They will be overwritten
   or deleted by the plugin.

 * I tried running `php wp-cron.php` but there are lots of warnings regarding `Undefined
   index: HTTP_HOST`.
 * Also, are there known bad interactions with cache plugins?
 * I purged the CSS and JS files, but the newly created merged files never get minified,
   it doesn’t matter what.

 * Are you running wp-cron.php via command line or on your browser? That might explain
   the undefined index.
 * We have had other cache plugins conflict in the past. Are you able to disable
   your other plugins and see if that resolves it?
 * Also are you able to paste a log of one of your files?

 * Sorry, but I gave up your plugin for now; I won’t be able to send any logs.
 * I was running `wp-cron` via CLI just to ensure it was running, not default for
   that blog.

 * Ok, I’ll mark this as resolved. Feel free to re-open if you try MMR again.
