 * After reading the reviews decided to give it a shot. Moments later we are completely
   offline and unable to restart our servers. I’ll change my review if support proves
   helpful.

 * that’s a painful experience ianchin.
 * some questions/ tips;
    * autoptimize is only active on the frontend, you should(
   have) be(en) able to still log in on the backend and disable AO * once you’re
   on the settings-page, you could disable HTML, CSS or JS optimization to see which
   one is causing this * the [CSS minimizer AO uses](https://github.com/tubalmartin/YUI-CSS-compressor-PHP-port)
   is very regex-intensive and as such sometimes crashes violently. [as per the FAQ](https://wordpress.org/plugins/autoptimize/faq/)
   you can switch to the older (less performant) legacy minifier * minifiers are
   a jealous bunch, make sure you don’t have any other plugin active that does JS/
   CSS or HTML minification * make sure your Apache (if you’re running that as webserver,
   that is) has AllowOverrides set to All, else it is possible that the htaccess
   provided by AO breaks and requests for optimized CSS/ JS result in a HTTP500 
   error/ internal server error * your phperror log (if you have that configured)
   might have valuable information on what went wrong as well
 * hope some of these prove helpful 😉

 * Thanks for the quick response! We serve about 200K PVs a day so job #1 was getting
   the site back up which we did by pulling the plugin. Really should not have played
   around w/ it in a live environment the way I did. Will review your tips and see
   if we can’t get it going on our dev server. Thanks again!

 * ah, 200K pageviews a day … if you have page- or even request-specific (inline)
   JS (or CSS) then AO will try to re-optimize continuously (as the cache would 
   not contain the already optimized code given the page-specific code) which would
   indeed generate a huge load (which you would not have seen on DEV anyway).
 * you can disable aggregation of inline JS/ CSS using the API (see [this sticky forum post](https://wordpress.org/support/topic/solving-cache-size-the-easiest-way?replies=23)).
   [The upcoming AO 2.0](https://github.com/futtta/autoptimize) will have a option
   on the settings page to enable/ disable aggregation of inline code.

 * Hi IanChin;
    Have you already had a chance to look further into what was happening
   here? Anything I could help you with?
